Alright is a python wrapper that helps you automate WhatsApp web using python, giving you the capability to send messages, images, video, and files to both saved and unsaved contacts without having to rescan the QR code every time.
I was looking for a way to control and automate WhatsApp web with Python; I came across some very nice libraries and wrappers implementations, including:
So I tried
pywhatkit, a well crafted to be used, but its implementations require you to open a new browser tab and scan QR code every time you send a message, no matter if it’s the same person, which was a deal-breaker for using it.
I then tried
which is based onyowsupand require you to do some registration with
yowsupbefore using it of which after a bit of googling, I got scared of having my number blocked. So I went for the next option.
I then went for WebWhatsapp-Wrapper. It has some good documentation and recent commits so I had hoped it is going to work. But It didn’t for me, and after having a couple of errors, I abandoned it to look for the next alternative.
PyWhatsapp by shauryauppal, which was more of a CLI tool than a wrapper, surprisingly worked. Its approach allows you to dynamically send WhatsApp messages to unsaved contacts without rescanning QR-code every time.
So what I did is refactoring the implementation of that tool to be more of a wrapper to easily allow people to run different scripts on top of it. Instead of just using it as a tool, I then thought of sharing the codebase with people who might struggle to do this as I did.

Simple to read and compose
Python has an improved sentence structure - one that is like the English language. New engineers for Python can undoubtedly understand where they stand in the development process. The simplicity of composing allows quick application building.
The motivation behind building Python, as said by its maker Guido Van Rossum, was to empower even beginner engineers to comprehend the programming language. The simple coding likewise permits developers to roll out speedy improvements without getting confused by pointless subtleties.
Utilized by the best
Alright - Python isn't simply one more programming language. It should have something, which is the reason the business giants use it. Furthermore, that too for different purposes. Developers at Google use Python to assemble framework organization systems, parallel information pusher, code audit, testing and QA, and substantially more. Netflix utilizes Python web development services for its recommendation algorithm and media player.
Massive community support
Python has a steadily developing community that offers enormous help. From amateurs to specialists, there's everybody. There are a lot of instructional exercises, documentation, and guides accessible for Python web development solutions.
Today, numerous universities start with Python, adding to the quantity of individuals in the community. Frequently, Python designers team up on various tasks and help each other with algorithmic, utilitarian, and application critical thinking.
Python is the greatest supporter of data science, Machine Learning, and Artificial Intelligence at any enterprise software development company. Its utilization cases in cutting edge applications are the most compelling motivation for its prosperity. Python is the second most well known tool after R for data analytics.
The simplicity of getting sorted out, overseeing, and visualizing information through unique libraries makes it ideal for data based applications. TensorFlow for neural networks and OpenCV for computer vision are two of Python's most well known use cases for Machine learning applications.
Thinking about the advances in programming and innovation, Python is a YES for an assorted scope of utilizations. Game development, web application development services, GUI advancement, ML and AI improvement, Enterprise and customer applications - every one of them uses Python to its full potential.
The disadvantages of Python web improvement arrangements are regularly disregarded by developers and organizations because of the advantages it gives. They focus on quality over speed and performance over blunders. That is the reason it's a good idea to utilize Python for building the applications of the future.

At the end of 2019, Python is one of the fastest-growing programming languages. More than 10% of developers have opted for Python development.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
Table of Contents hide
III Built-in data types in Python
The Size and declared value and its sequence of the object can able to be modified called mutable objects.
Mutable Data Types are list, dict, set, byte array
The Size and declared value and its sequence of the object can able to be modified.
Immutable data types are int, float, complex, String, tuples, bytes, and frozen sets.
id() and type() is used to know the Identity and data type of the object
a**=str(“Hello python world”)****#str**
Numbers are stored in numeric Types. when a number is assigned to a variable, Python creates Number objects.
Python supports 3 types of numeric data.
int (signed integers like 20, 2, 225, etc.)
float (float is used to store floating-point numbers like 9.8, 3.1444, 89.52, etc.)
complex (complex numbers like 8.94j, 4.0 + 7.3j, etc.)
A complex number contains an ordered pair, i.e., a + ib where a and b denote the real and imaginary parts respectively).
The string can be represented as the sequence of characters in the quotation marks. In python, to define strings we can use single, double, or triple quotes.
# String Handling
#single (') Quoted String
# Double (") Quoted String
# triple (‘’') (“”") Quoted String
In python, string handling is a straightforward task, and python provides various built-in functions and operators for representing strings.
The operator “+” is used to concatenate strings and “*” is used to repeat the string.

Drivers in Selenium are a vital rather a must for Browser automation. Selenium library in Python or in any other programming language uses the particular Browser’s driver to control browsers with their actions, add functionality to it, and in all manipulate data (webpage) in it.
Contrary to the most common way of declaring a Browser’s Driver which is most common, but often may result in incompatibility issues. There are multiple ways (not so common) to install, initialize web drivers in your Python code.
The foremost point of error in Selenium occurs when the browser’s driver’s version doesn’t match with the browser’s version, for which compatibility issue arises. So, to start with, you must always use the driver with the same version as that of the Web Browser(Google Chrome, Mozilla Firefox, Apple Safari, or any other) which you intend to use for automation.
Downloading and installing Web Drivers is completely safe because these drivers are maintained by the Official Browser Companies and updated accordingly, for testing and automation purposes of their browser and webpages.
Check with your browser which you intend to automate for its version and download the driver from the below references accordingly:
|Web Browser||Driver Download Reference|
|Apple Safari||Already built-in|
Let’s now look at how we can use the selenium web drivers.
Advantage: No need to care about lengthy setup or figuring out of Environment variable
Disadvantage: Makes the code less flexible and subject to manual changes for every update
driver = webdriver.Chrome('path/to/chromedriver") driver = webdriver.Chrome('C://software/chromedriver.exe') #driver located at the specified location driver = webdriver.Chrome('chromedriver.exe') #driver located in the same directory as of the python script file #other way service = Service(executable_path="/path/to/chromedriver") driver = webdriver.Chrome(service=service)
Advantage: No hassle of specifying the path to the driver
Disadvantage: No update functionality
To set the Environment Path Variable, go to your command prompt and type in the following command:In place of “C:\WebDriver\bin” in the below command, use the path (install location) of the driver.
setx PATH "%PATH%;C:\WebDriver\bin"
If you find this way difficult, then you may search for Environment Variable in your Windows Start Menu and click open -“Edit the system environment variables“. After that, from the pop-up window select “Environment Variables” to open another pop-up window.
From the System Variables option, select open Path and now click on New to introduce a new path variable. Paste the location of your web driver in it, then OK, OK, and finally again OK, in all windows.
The last and probably the most useful method to use is the Web Driver in your Python code. On selecting, automatic updating in Web Browser, the device only updates the browser and not the installed driver, in this case upon execution of python script the code gives error for not equal versions of the browser and driver.
Advantage: No version compatibility issues and help easily switch between multiple browsers
Disadvantage: Maybe a bit difficult to set up for beginners
Install the driver manager
pip install webdriver-manager
Import the manager
from selenium import webdriver from webdriver_manager.chrome import ChromeDriverManager # --> for Chrome #from webdriver_manager.firefox import GeckoDriverManager # --> for Firefox
Now as we have installed and imported the manager, we use it in our code like –
install() method to get the location used by the manager and pass it into a loc_service class. This method informs about the location of the installed web driver by itself.
driver = webdriver.Chrome(ChromeDriverManager().install()) # --> for Chrome #driver = webdriver.Firefox(executable_path=GeckoDriverManager().install()) #--> for Firefox
For any other browser, you may check the official GitHub repository of the driver manager software.
That’s it for the tutorial. Contrary to the popular methods of using the web drivers in Selenium, in this tutorial you learned about the other and maybe advantageous methods to perform the same.
