## How to Build a Number Guessing Game in Python

In this project, you will create a simple number guessing game that allows the user to guess a random number between 1 and 100. The program will give hints to the user after each guess, indicating whether their guess was too high or too low, until the user guesses the correct number.

Code:

``````import random

secret_number = random.randint(1, 100)

while True:
guess = int(input("Guess the number between 1 and 100: "))

if guess == secret_number:
print("Congratulations! You guessed the number!")
break
elif guess < secret_number:
print("Too low! Try again.")
else:
print("Too high! Try again.")
``````

Explanation:

• Start by importing the `random` module, which will allow you to generate a random number.
• Generate a random number between 1 and 100 using the `randint()` function from the `random` module, and assign it to a variable.
• Create a loop that allows the user to guess the number until they guess correctly. Inside the loop, prompt the user to enter their guess using the `input()` function, and convert their input to an integer using the `int()` function.
• Add a conditional statement inside the loop that checks whether the user's guess is correct, too high, or too low. If the guess is correct, print a congratulatory message and break out of the loop. If the guess is too high or too low, print a hint message to help the user guess the number correctly.
• Run the program and play the number guessing game!

## How to Build a Simple Password Generator in Python

A password generator, as the name implies, generates a random password of a particular length using different combination of characters, and special characters.

Code:

``````import random
import string

"""This function generates a random password
of a given length using a combination of
uppercase letters, lowercase letters,
digits, and special characters"""

# Define a string containing all possible characters
all_chars = string.ascii_letters + string.digits + string.punctuation

# Generate a password using a random selection of characters
password = "".join(random.choice(all_chars) for i in range(length))

# Test the function by generating a password of length 10
``````

Explanation:

• We import the `random` and `string` modules which we use to generate random values and work with strings, respectively.
• Next, we define a function called `generate_password` that takes a single parameter `length`, which specifies the length of the password that needs to be generated.
• Inside the function, we define a string called `all_chars` which contains all possible characters that can be used to generate the password. We use the `string.ascii_letters`, `string.digits`, and `string.punctuation` constants to create this string.
• We then use list comprehension to generate a list of `length` random characters from the `all_chars` string using the `random.choice()` function. Finally, we join these characters together into a single string using the `"".join()` function and return the result.
• To test the function, we call it with an argument of 10 to generate a password of length 10 and print the result.

Note that this is a very simple password generator and may not be suitable for use in real-world scenarios where security is a concern.

## How to Build a Password Checker in Python

We will build a password checker in this section. Its job is to check if a password is strong enough based on some of the criteria we set. It'll print an error if any of the password criteria isn't met.

Code:

``````# Define a function to check if the password is strong enough
# Define the criteria for a strong password
min_length = 8
has_uppercase = False
has_lowercase = False
has_digit = False
has_special_char = False
special_chars = "!@#\$%^&*()-_=+[{]}\|;:',<.>/?"

# Check the length of the password
return False

# Check if the password contains an uppercase letter, lowercase letter, digit, and special character
if char.isupper():
has_uppercase = True
elif char.islower():
has_lowercase = True
elif char.isdigit():
has_digit = True
elif char in special_chars:
has_special_char = True

# Print an error message for each missing criteria
if not has_uppercase:
print("Password must contain at least one uppercase letter!")
return False
if not has_lowercase:
print("Password must contain at least one lowercase letter!")
return False
if not has_digit:
print("Password must contain at least one digit!")
return False
if not has_special_char:
print("Password must contain at least one special character!")
return False

# If all criteria are met, print a success message
return True

# Prompt the user to enter a password and check if it meets the criteria
``````

Explanation:

• In this code, we define a function called `password_checker()` that takes a password as an argument and checks if it meets certain criteria for strength.
• We first define the criteria for a strong password – a minimum length of 8 characters, at least one uppercase letter, one lowercase letter, one digit, and one special character.
• We then check the length of the password and whether it contains the required types of characters using a for loop that iterates through each character in the password.
• If the password fails to meet any of the criteria, we print an error message and return `False` to indicate that the password is not strong enough. Otherwise, we print a success message and return `True`.
• Finally, we prompt the user to enter a password using the `input()` function and pass it to the `password_checker()` function to check if it meets the criteria.

## How to Build a Web Scraper in Python

A web scraper scrapes/gets data from webpages and saves it in any format we want, either .csv or .txt. We will build a simple web scraper in this section using a Python library called Beautiful Soup.

Code:

``````import requests
from bs4 import BeautifulSoup

# Set the URL of the webpage you want to scrape
url = 'https://www.example.com'

# Send an HTTP request to the URL and retrieve the HTML content
response = requests.get(url)

# Create a BeautifulSoup object that parses the HTML content
soup = BeautifulSoup(response.content, 'html.parser')

# Find all the links on the webpage

# Print the text and href attribute of each link
``````

Explanation:

• In this code, we first import the `requests` and `BeautifulSoup` modules which are used to make HTTP requests and parse HTML content, respectively.
• Next, we set the URL of the webpage that we want to scrape in a variable called `url`.
• We then use the `requests.get()` function to send an HTTP GET request to the URL and retrieve the HTML content of the webpage as a response.
• We create a `BeautifulSoup` object called `soup` that parses the HTML content of the response using the `html.parser` parser.
• We then use the `soup.find_all()` method to find all the links on the webpage and store them in a variable called `links`.
• Finally, we use a for loop to iterate through each link in `links` and print the text and href attribute of each link using the `link.get()` method.

## How to Build a Currency Converter in Python

A currency converter is a program that helps users convert the value of one currency into another currency. You can use it for a variety of purposes, such as calculating the cost of international purchases, estimating travel expenses, or analyzing financial data.

Note: we will use the ExchangeRate-API to get the exchange rate data, which is a free and open-source API for currency exchange rates. But there are other APIs available that may have different usage limits or requirements.

Code:

``````# Import the necessary modules
import requests

# Define a function to convert currencies
def currency_converter(amount, from_currency, to_currency):
# Set the API endpoint for currency conversion
api_endpoint = f"https://api.exchangerate-api.com/v4/latest/{from_currency}"

# Send a GET request to the API endpoint
response = requests.get(api_endpoint)

# Get the JSON data from the response
data = response.json()

# Extract the exchange rate for the target currency
exchange_rate = data["rates"][to_currency]

# Calculate the converted amount
converted_amount = amount * exchange_rate

# Return the converted amount
return converted_amount

# Prompt the user to enter the amount, source currency, and target currency
amount = float(input("Enter the amount: "))
from_currency = input("Enter the source currency code: ").upper()
to_currency = input("Enter the target currency code: ").upper()

# Convert the currency and print the result
result = currency_converter(amount, from_currency, to_currency)
print(f"{amount} {from_currency} is equal to {result} {to_currency}")
``````

Explanation:

• In this code, we define a function called `currency_converter()` that takes an amount, source currency code, and target currency code as arguments and returns the converted amount.
• We first set the API endpoint for currency conversion using the `from_currency` parameter and the `requests` module to send a GET request to the endpoint.
• We then extract the exchange rate for the target currency from the JSON data returned by the API using the `to_currency` parameter and calculate the converted amount by multiplying the exchange rate with the `amount` parameter.
• Finally, we prompt the user to enter the `amount`, `from_currency`, and `to_currency` using the `input()` function and pass them to the `currency_converter()` function to convert the currency. The converted amount is then printed using string formatting.

## Conclusion

All these projects are very simple and easy to build. If you really want to improve your Python skills, I'd advise you to take the code, modify and edit it, and build upon it. You can turn many of these simple projects into much more complex applications if you want.

## Introduction

We are back with another exciting and much-talked-about Rails tutorial on how to use Hotwire with the Rails application. This Hotwire Rails tutorial is an alternate method for building modern web applications that consume a pinch of JavaScript.

Rails 7 Hotwire is the default front-end framework shipped with Rails 7 after it was launched. It is used to represent HTML over the wire in the Rails application. Previously, we used to add a hotwire-rails gem in our gem file and then run rails hotwire: install. However, with the introduction of Rails 7, the gem got deprecated. Now, we use turbo-rails and stimulus rails directly, which work as Hotwire’s SPA-like page accelerator and Hotwire’s modest JavaScript framework.

## What is Hotwire?

Hotwire is a package of different frameworks that help to build applications. It simplifies the developer’s work for writing web pages without the need to write JavaScript, and instead sending HTML code over the wire.

Introduction to The Hotwire Framework:

### 1. Turbo:

It uses simplified techniques to build web applications while decreasing the usage of JavaScript in the application. Turbo offers numerous handling methods for the HTML data sent over the wire and displaying the application’s data without actually loading the entire page. It helps to maintain the simplicity of web applications without destroying the single-page application experience by using the below techniques:

Turbo Frames: Turbo Frames help to load the different sections of our markup without any dependency as it divides the page into different contexts separately called frames and updates these frames individually.
Turbo Drive: Every link doesn’t have to make the entire page reload when clicked. Only the HTML contained within the tag will be displayed.
Turbo Streams: To add real-time features to the application, this technique is used. It helps to bring real-time data to the application using CRUD actions.

### 2. Stimulus

It represents the JavaScript framework, which is required when JS is a requirement in the application. The interaction with the HTML is possible with the help of a stimulus, as the controllers that help those interactions are written by a stimulus.

Not much information is available about Strada as it has not been officially released yet. However, it works with native applications, and by using HTML bridge attributes, interaction is made possible between web applications and native apps.

Simple diagrammatic representation of Hotwire Stack:

## Prerequisites For Hotwire Rails Tutorial

As we are implementing the Ruby on Rails Hotwire tutorial, make sure about the following installations before you can get started.

• Ruby on Rails
• Hotwire gem
• PostgreSQL/SQLite (choose any one database)
• Turbo Rails
• Stimulus.js

Looking for an enthusiastic team of ROR developers to shape the vision of your web project?
Contact Bacancy today and hire Ruby developers to start building your dream project!

## Create a new Rails Project

Find the following commands to create a rails application.

``````mkdir ~/projects/railshotwire
cd ~/projects/railshotwire
echo "source 'https://rubygems.org'" > Gemfile
echo "gem 'rails', '~> 7.0.0'" >> Gemfile
bundle install
bundle exec rails new . --force -d=postgresql``````

Now create some files for the project, up till now no usage of Rails Hotwire can be seen.
Fire the following command in your terminal.

• For creating a default controller for the application
``````echo "class HomeController < ApplicationController" > app/controllers/home_controller.rb
echo "end" >> app/controllers/home_controller.rb``````
• For creating another controller for the application
``````echo "class OtherController < ApplicationController" > app/controllers/other_controller.rb
echo "end" >> app/controllers/home_controller.rb``````
• For creating routes for the application
``````echo "Rails.application.routes.draw do" > config/routes.rb
echo '  get "home/index"' >> config/routes.rb
echo '  get "other/index"' >> config/routes.rb
echo '  root to: "home#index"' >> config/routes.rb
echo 'end' >> config/routes.rb``````
• For creating a default view for the application
``````mkdir app/views/home
echo '<h1>This is Rails Hotwire homepage</h1>' > app/views/home/index.html.erb
echo '<div><%= link_to "Enter to other page", other_index_path %></div>' >> app/views/home/index.html.erb
``````
• For creating another view for the application
``````mkdir app/views/other
echo '<h1>This is Another page</h1>' > app/views/other/index.html.erb
``````
• For creating a database and schema.rb file for the application
``````bin/rails db:create
bin/rails db:migrate``````
• For checking the application run bin/rails s and open your browser, your running application will have the below view.

Additionally, you can clone the code and browse through the project. Here’s the source code of the repository: Rails 7 Hotwire application

Now, let’s see how Hotwire Rails can work its magic with various Turbo techniques.

## Hotwire Rails: Turbo Drive

Now click on go to another page link that appears on the home page to redirect from the home page to another page. In our Network tab, we can see that this action of navigation is achieved via XHR. It appears only the part inside HTML is reloaded, here neither the CSS is reloaded nor the JS is reloaded when the navigation action is performed.

By performing this action we can see that Turbo Drive helps to represent the HTML response without loading the full page and only follows redirect and reindeer HTML responses which helps to make the application faster to access.

## Hotwire Rails: Turbo Frame

This technique helps to divide the current page into different sections called frames that can be updated separately independently when new data is added from the server.
Below we discuss the different use cases of Turbo frame like inline edition, sorting, searching, and filtering of data.

Let’s perform some practical actions to see the example of these use cases.

Make changes in the app/controllers/home_controller.rb file

#CODE

``````class HomeController < ApplicationController
def turbo_frame_form
end

def turbo_frame submit
extracted_anynumber = params[:any][:anynumber]
render :turbo_frame_form, status: :ok, locals: {anynumber: extracted_anynumber,      comment: 'turbo_frame_submit ok' }
end
end``````

Add app/views/home/turbo_frame_form.html.erb file to the application and add this content inside the file.

#CODE

``````<section>

<%= turbo_frame_tag 'anyframe' do %>

<div>
<h2>Frame view</h2>
<%= form_with scope: :any, url: turbo_frame_submit_path, local: true do |form| %>
<%= form.label :anynumber, 'Type an integer (odd or even)', 'class' => 'my-0  d-inline'  %>
<%= form.text_field :anynumber, type: 'number', 'required' => 'true', 'value' => "#{local_assigns[:anynumber] || 0}",  'aria-describedby' => 'anynumber' %>
<%= form.submit 'Submit this number', 'id' => 'submit-number' %>
<% end %>
</div>
<div>
<h2>Data of the view</h2>
<pre style="font-size: .7rem;"><%= JSON.pretty_generate(local_assigns) %></pre>
</div>

<% end %>

</section>``````

#CODE

``````Rails.application.routes.draw do
get 'home/index'
get 'other/index'

get '/home/turbo_frame_form' => 'home#turbo_frame_form', as: 'turbo_frame_form'
post '/home/turbo_frame_submit' => 'home#turbo_frame_submit', as: 'turbo_frame_submit'

root to: "home#index"
end``````
• Next step is to change homepage view in app/views/home/index.html.erb

#CODE

``````<h1>This is Rails Hotwire home page</h1>
<div><%= link_to "Enter to other page", other_index_path %></div>

<%= turbo_frame_tag 'anyframe' do %>
<div>
<h2>Home view</h2>
<%= form_with scope: :any, url: turbo_frame_submit_path, local: true do |form| %>
<%= form.label :anynumber, 'Type an integer (odd or even)', 'class' => 'my-0  d-inline'  %>
<%= form.text_field :anynumber, type: 'number', 'required' => 'true', 'value' => "#{local_assigns[:anynumber] || 0}",  'aria-describedby' => 'anynumber' %>
<%= form.submit 'Submit this number', 'id' => 'submit-number' %>
<% end %>
<div>
<% end %>``````

After making all the changes, restart the rails server and refresh the browser, the default view will appear on the browser.

Now in the field enter any digit, after entering the digit click on submit button, and as the submit button is clicked we can see the Turbo Frame in action in the below screen, we can observe that the frame part changed, the first title and first link didn’t move.

## Hotwire Rails: Turbo Streams

Turbo Streams deliver page updates over WebSocket, SSE or in response to form submissions by only using HTML and a series of CRUD-like operations, you are free to say that either

• Update the piece of HTML while responding to all the other actions like the post, put, patch, and delete except the GET action.
• Transmit a change to all users, without reloading the browser page.

This transmit can be represented by a simple example.

• Make changes in app/controllers/other_controller.rb file of rails application

#CODE

``````class OtherController < ApplicationController

def post_something
respond_to do |format|
format.turbo_stream {  }
end
end

end``````

Add the below line in routes.rb file of the application

#CODE

``post '/other/post_something' => 'other#post_something', as: 'post_something'``

Superb! Rails will now attempt to locate the app/views/other/post_something.turbo_stream.erb template at any moment the ‘/other/post_something’ endpoint is reached.

For this, we need to add app/views/other/post_something.turbo_stream.erb template in the rails application.

#CODE

``````<turbo-stream action="append" target="messages">
<template>
<div id="message_1">This changes the existing message!</div>
</template>
</turbo-stream>
``````

This states that the response will try to append the template of the turbo frame with ID “messages”.

Now change the index.html.erb file in app/views/other paths with the below content.

#CODE

``````<h1>This is Another page</h1>

<div style="margin-top: 3rem;">
<%= form_with scope: :any, url: post_something_path do |form| %>
<%= form.submit 'Post any message %>
<% end %>
<turbo-frame id="messages">
<div>An empty message</div>
</turbo-frame>
</div>``````
• After making all the changes, restart the rails server and refresh the browser, and go to the other page.

• Once the above screen appears, click on the Post any message button

This action shows that after submitting the response, the Turbo Streams help the developer to append the message, without reloading the page.

Another use case we can test is that rather than appending the message, the developer replaces the message. For that, we need to change the content of app/views/other/post_something.turbo_stream.erb template file and change the value of the action attribute from append to replace and check the changes in the browser.

#CODE

``````<turbo-stream action="replace" target="messages">
<template>
<div id="message_1">This changes the existing message!</div>
</template>
</turbo-stream>``````

When we click on Post any message button, the message that appear below that button will get replaced with the message that is mentioned in the app/views/other/post_something.turbo_stream.erb template

## Stimulus

There are some cases in an application where JS is needed, therefore to cover those scenarios we require Hotwire JS tool. Hotwire has a JS tool because in some scenarios Turbo-* tools are not sufficient. But as we know that Hotwire is used to reduce the usage of JS in an application, Stimulus considers HTML as the single source of truth. Consider the case where we have to give elements on a page some JavaScript attributes, such as data controller, data-action, and data target. For that, a stimulus controller that can access elements and receive events based on those characteristics will be created.

Make a change in app/views/other/index.html.erb template file in rails application

#CODE

``````<h1>This is Another page</h1>

<div style="margin-top: 2rem;">
<%= form_with scope: :any, url: post_something_path do |form| %>
<%= form.submit 'Post something' %>
<% end %>
<turbo-frame id="messages">
<div>An empty message</div>
</turbo-frame>
</div>

<div style="margin-top: 2rem;">
<h2>Stimulus</h2>
<div data-controller="hello">
<input data-hello-target="name" type="text">
<button data-action="click->hello#greet">
Greet
</button>
<span data-hello-target="output">
</span>
</div>
</div>``````

Make changes in the hello_controller.js in path app/JavaScript/controllers and add a stimulus controller in the file, which helps to bring the HTML into life.

#CODE

``````import { Controller } from "@hotwired/stimulus"

export default class extends Controller {
static targets = [ "name", "output" ]

greet() {
this.outputTarget.textContent =
`Hello, \${this.nameTarget.value}!`
}
}``````

Go to your browser after making the changes in the code and click on Enter to other page link which will navigate to the localhost:3000/other/index page there you can see the changes implemented by the stimulus controller that is designed to augment your HTML with just enough behavior to make it more responsive.

With just a little bit of work, Turbo and Stimulus together offer a complete answer for applications that are quick and compelling.

Using Rails 7 Hotwire helps to load the pages at a faster speed and allows you to render templates on the server, where you have access to your whole domain model. It is a productive development experience in ROR, without compromising any of the speed or responsiveness associated with SPA.

## Top Android Projects with Source Code

Android Projects with Source Code – Your entry pass into the world of Android

These project ideas are simple suggestions to help you deal with the difficulty of choosing the correct projects. In this article, we’ll see the project ideas from beginners level and later we’ll move on to intermediate to advance.

## Android Projects with Source Code

Before working on real-time projects, it is recommended to create a sample hello world project in android studio and get a flavor of project creation as well as execution: Create your first android project

### Android Projects for beginners

#### 1. Calculator

Android Project: A calculator will be an easy application if you have just learned Android and coding for Java. This Application will simply take the input values and the operation to be performed from the users. After taking the input it’ll return the results to them on the screen. This is a really easy application and doesn’t need use of any particular package.

To make a calculator you’d need Android IDE, Kotlin/Java for coding, and for layout of your application, you’d need XML or JSON. For this, coding would be the same as that in any language, but in the form of an application. Not to forget creating a calculator initially will increase your logical thinking.

Once the user installs the calculator, they’re ready to use it even without the internet. They’ll enter the values, and the application will show them the value after performing the given operations on the entered operands.

Source Code: Simple Calculator Project

#### 2. A Reminder App

Android Project: This is a good project for beginners. A Reminder App can help you set reminders for different events that you have throughout the day. It’ll help you stay updated with all your tasks for the day. It can be useful for all those who are not so good at organizing their plans and forget easily. This would be a simple application just whose task would be just to remind you of something at a particular time.

To make a Reminder App you need to code in Kotlin/Java and design the layout using XML or JSON. For the functionality of the app, you’d need to make use of AlarmManager Class and Notifications in Android.

In this, the user would be able to set reminders and time in the application. Users can schedule reminders that would remind them to drink water again and again throughout the day. Or to remind them of their medications.

#### 3. Quiz Application

Android Project: Another beginner’s level project Idea can be a Quiz Application in android. Here you can provide the users with Quiz on various general knowledge topics. These practices will ensure that you’re able to set the layouts properly and slowly increase your pace of learning the Android application development. In this you’ll learn to use various Layout components at the same time understanding them better.

To make a quiz application you’ll need to code in Java and set layouts using xml or java whichever you prefer. You can also use JSON for the layouts whichever preferable.

In the app, questions would be asked and answers would be shown as multiple choices. The user selects the answer and gets shown on the screen if the answers are correct. In the end the final marks would be shown to the users.

#### 4. Simple Tic-Tac-Toe

Android Project: Tic-Tac-Toe is a nice game, I guess most of you all are well aware of it. This will be a game for two players. In this android game, users would be putting X and O in the given 9 parts of a box one by one. The first player to arrange X or O in an adjacent line of three wins.

To build this game, you’d need Java and XML for Android Studio. And simply apply the logic on that. This game will have a set of three matches. So, it’ll also have a scoreboard. This scoreboard will show the final result at the end of one complete set.

Upon entering the game they’ll enter their names. And that’s when the game begins. They’ll touch one of the empty boxes present there and get their turn one by one. At the end of the game, there would be a winner declared.

Source Code: Tic Tac Toe Game Project

#### 5. Stopwatch

Android Project: A stopwatch is another simple android project idea that will work the same as a normal handheld timepiece that measures the time elapsed between its activation and deactivation. This application will have three buttons that are: start, stop, and hold.

This application would need to use Java and XML. For this application, we need to set the timer properly as it is initially set to milliseconds, and that should be converted to minutes and then hours properly. The users can use this application and all they’d need to do is, start the stopwatch and then stop it when they are done. They can also pause the timer and continue it again when they like.

#### 6. To Do App

Android Project: This is another very simple project idea for you as a beginner. This application as the name suggests will be a To-Do list holding app. It’ll store the users schedules and their upcoming meetings or events. In this application, users will be enabled to write their important notes as well. To make it safe, provide a login page before the user can access it.

So, this app will have a login page, sign-up page, logout system, and the area to write their tasks, events, or important notes. You can build it in android studio using Java and XML at ease. Using XML you can build the user interface as user-friendly as you can. And to store the users’ data, you can use SQLite enabling the users to even delete the data permanently.
