Title: Create a GUI Marksheet using Tkinter
In this video, I am Creating a python GUI mark sheet. Where credits of each subject are given, enter the grades obtained in each subject and click on Submit. The credits per subject, the total credits as well as the SGPA is displayed after being calculated automatically. Use Tkinter to create the GUI interface.
Python offers multiple options for developing a GUI (Graphical User Interface). Out of all the GUI methods, Tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Python with Tkinter outputs the fastest and easiest way to create GUI applications. Creating a GUI using Tkinter is an easy task.
To create a Tkinter:
●Importing the module – Tkinter
●Create the main window (container)
●Add any number of widgets to the main window
●Apply the event Trigger on the widgets.
Let’s create a GUI based simple mark sheet using the Python Tkinter module, which can create a mark sheet based on the marks entered per subject.
Source Code & Link:
#python #web-development #programming #developer #data-science
Install via pip:
$ pip install pytumblr
Install from source:
$ git clone https://github.com/tumblr/pytumblr.git $ cd pytumblr $ python setup.py install
pytumblr.TumblrRestClient is the object you'll make all of your calls to the Tumblr API through. Creating one is this easy:
client = pytumblr.TumblrRestClient( '<consumer_key>', '<consumer_secret>', '<oauth_token>', '<oauth_secret>', ) client.info() # Grabs the current user information
Two easy ways to get your credentials to are:
interactive_console.pytool (if you already have a consumer key & secret)
client.info() # get information about the authenticating user client.dashboard() # get the dashboard for the authenticating user client.likes() # get the likes for the authenticating user client.following() # get the blogs followed by the authenticating user client.follow('codingjester.tumblr.com') # follow a blog client.unfollow('codingjester.tumblr.com') # unfollow a blog client.like(id, reblogkey) # like a post client.unlike(id, reblogkey) # unlike a post
client.blog_info(blogName) # get information about a blog client.posts(blogName, **params) # get posts for a blog client.avatar(blogName) # get the avatar for a blog client.blog_likes(blogName) # get the likes on a blog client.followers(blogName) # get the followers of a blog client.blog_following(blogName) # get the publicly exposed blogs that [blogName] follows client.queue(blogName) # get the queue for a given blog client.submission(blogName) # get the submissions for a given blog
PyTumblr lets you create all of the various types that Tumblr supports. When using these types there are a few defaults that are able to be used with any post type.
The default supported types are described below.
We'll show examples throughout of these default examples while showcasing all the specific post types.
Creating a photo post
Creating a photo post supports a bunch of different options plus the described default options * caption - a string, the user supplied caption * link - a string, the "click-through" url for the photo * source - a string, the url for the photo you want to use (use this or the data parameter) * data - a list or string, a list of filepaths or a single file path for multipart file upload
#Creates a photo post using a source URL client.create_photo(blogName, state="published", tags=["testing", "ok"], source="https://68.media.tumblr.com/b965fbb2e501610a29d80ffb6fb3e1ad/tumblr_n55vdeTse11rn1906o1_500.jpg") #Creates a photo post using a local filepath client.create_photo(blogName, state="queue", tags=["testing", "ok"], tweet="Woah this is an incredible sweet post [URL]", data="/Users/johnb/path/to/my/image.jpg") #Creates a photoset post using several local filepaths client.create_photo(blogName, state="draft", tags=["jb is cool"], format="markdown", data=["/Users/johnb/path/to/my/image.jpg", "/Users/johnb/Pictures/kittens.jpg"], caption="## Mega sweet kittens")
Creating a text post
Creating a text post supports the same options as default and just a two other parameters * title - a string, the optional title for the post. Supports markdown or html * body - a string, the body of the of the post. Supports markdown or html
#Creating a text post client.create_text(blogName, state="published", slug="testing-text-posts", title="Testing", body="testing1 2 3 4")
Creating a quote post
Creating a quote post supports the same options as default and two other parameter * quote - a string, the full text of the qote. Supports markdown or html * source - a string, the cited source. HTML supported
#Creating a quote post client.create_quote(blogName, state="queue", quote="I am the Walrus", source="Ringo")
Creating a link post
#Create a link post client.create_link(blogName, title="I like to search things, you should too.", url="https://duckduckgo.com", description="Search is pretty cool when a duck does it.")
Creating a chat post
Creating a chat post supports the same options as default and two other parameters * title - a string, the title of the chat post * conversation - a string, the text of the conversation/chat, with diablog labels (no html)
#Create a chat post chat = """John: Testing can be fun! Renee: Testing is tedious and so are you. John: Aw. """ client.create_chat(blogName, title="Renee just doesn't understand.", conversation=chat, tags=["renee", "testing"])
Creating an audio post
Creating an audio post allows for all default options and a has 3 other parameters. The only thing to keep in mind while dealing with audio posts is to make sure that you use the external_url parameter or data. You cannot use both at the same time. * caption - a string, the caption for your post * external_url - a string, the url of the site that hosts the audio file * data - a string, the filepath of the audio file you want to upload to Tumblr
#Creating an audio file client.create_audio(blogName, caption="Rock out.", data="/Users/johnb/Music/my/new/sweet/album.mp3") #lets use soundcloud! client.create_audio(blogName, caption="Mega rock out.", external_url="https://soundcloud.com/skrillex/sets/recess")
Creating a video post
Creating a video post allows for all default options and has three other options. Like the other post types, it has some restrictions. You cannot use the embed and data parameters at the same time. * caption - a string, the caption for your post * embed - a string, the HTML embed code for the video * data - a string, the path of the file you want to upload
#Creating an upload from YouTube client.create_video(blogName, caption="Jon Snow. Mega ridiculous sword.", embed="http://www.youtube.com/watch?v=40pUYLacrj4") #Creating a video post from local file client.create_video(blogName, caption="testing", data="/Users/johnb/testing/ok/blah.mov")
Editing a post
Updating a post requires you knowing what type a post you're updating. You'll be able to supply to the post any of the options given above for updates.
client.edit_post(blogName, id=post_id, type="text", title="Updated") client.edit_post(blogName, id=post_id, type="photo", data="/Users/johnb/mega/awesome.jpg")
Reblogging a Post
Reblogging a post just requires knowing the post id and the reblog key, which is supplied in the JSON of any post object.
client.reblog(blogName, id=125356, reblog_key="reblog_key")
Deleting a post
Deleting just requires that you own the post and have the post id
client.delete_post(blogName, 123456) # Deletes your post :(
A note on tags: When passing tags, as params, please pass them as a list (not a comma-separated string):
client.create_text(blogName, tags=['hello', 'world'], ...)
Getting notes for a post
In order to get the notes for a post, you need to have the post id and the blog that it is on.
data = client.notes(blogName, id='123456')
The results include a timestamp you can use to make future calls.
data = client.notes(blogName, id='123456', before_timestamp=data["_links"]["next"]["query_params"]["before_timestamp"])
# get posts with a given tag client.tagged(tag, **params)
This client comes with a nice interactive console to run you through the OAuth process, grab your tokens (and store them for future use).
pyyaml installed to run it, but then it's just:
$ python interactive-console.py
and away you go! Tokens are stored in
~/.tumblr and are also shared by other Tumblr API clients like the Ruby client.
The tests (and coverage reports) are run with nose, like this:
python setup.py test
A Graphical User Interface allows the user to interact with the application created on different platforms.
GUI interfaces use different indicators like audio indicators, graphical icons, different widgets which makes it highly interactive and user friendly rather than Command-Line applications which are not visually appealing and are text-based interactions.
Tkinter provides a GUI look to the standard python interface. It comes pre-installed with the standard versions of Python on Windows, Linux, and macOS. Tkinter is a Python binding to the Tk GUI toolkit which is why it is named Tkinter. It is the most commonly used python GUI toolkit due to a large variety of widgets it supports and its ease of use.
Tkinter provides powerful GUI based widgets and functions which create a visually appealing and highly creative application in just a few lines of codes. Tkinter is famous for creating a GUI application because it opens up in a new window where the user can interact with the application.
In this article, we will explore how we can create a GUI application with a variety of widgets that are available in Tkinter.
As Tkinter comes pre-installed with standard python installation so we will not be installing it although if you don’t have it installed you can install it using pip install tkinter.
We will create a form using Tkinter and the widgets it provides. So we will import Tkinter. Also, we will create a window that will initiate the Tk class.
import tkinter as tk
window = tk.Tk()
Now we will create the form using different widgets and wrapping them in a single loop.
We will start by setting the turtle of the window that will run our form. As I already mentioned that we need everything in a single loop so that everything displays at one go we will create the main loop and define all our widgets and functions before that.
window.title('Article Submission Form')
window.mainloop() #this will be the end of our form to wrap everything
This is the basic layout of the window we created with the title as we mentioned in the code.
We will start by adding Labels for different sections and adding a text box to those labels to the user input. We will also make the application window a bit large in size so that we can see everything clearly without maximizing. Here we will use the ‘place’ function which takes the X and Y coordinate values and displays the widgets accordingly.

Can you use WordPress for anything other than blogging? To your surprise, yes. WordPress is more than just a blogging tool, and it has helped thousands of websites and web applications to thrive. The use of WordPress powers around 40% of online projects, and today in our blog, we would visit some amazing uses of WordPress other than blogging.
What Is The Use Of WordPress?
WordPress is the most popular website platform in the world. It is the first choice of businesses that want to set a feature-rich and dynamic Content Management System. So, if you ask what WordPress is used for, the answer is – everything. It is a super-flexible, feature-rich and secure platform that offers everything to build unique websites and applications. Let’s start knowing them:
1. Multiple Websites Under A Single Installation
WordPress Multisite allows you to develop multiple sites from a single WordPress installation. You can download WordPress and start building websites you want to launch under a single server. Literally speaking, you can handle hundreds of sites from one single dashboard, which now needs applause.
It is a highly efficient platform that allows you to easily run several websites under the same login credentials. One of the best things about WordPress is the themes it has to offer. You can simply download them and plugin for various sites and save space on sites without losing their speed.
2. WordPress Social Network
WordPress can be used for high-end projects such as Social Media Network. If you don’t have the money and patience to hire a coder and invest months in building a feature-rich social media site, go for WordPress. It is one of the most amazing uses of WordPress. Its stunning CMS is unbeatable. And you can build sites as good as Facebook or Reddit etc. It can just make the process a lot easier.
To set up a social media network, you would have to download a WordPress Plugin called BuddyPress. It would allow you to connect a community page with ease and would provide all the necessary features of a community or social media. It has direct messaging, activity stream, user groups, extended profiles, and so much more. You just have to download and configure it.
If BuddyPress doesn’t meet all your needs, don’t give up on your dreams. You can try out WP Symposium or PeepSo. There are also several themes you can use to build a social network.
3. Create A Forum For Your Brand’s Community
Communities are very important for your business. They help you stay in constant connection with your users and consumers. And allow you to turn them into a loyal customer base. Meanwhile, there are many good technologies that can be used for building a community page – the good old WordPress is still the best.
It is the best community development technology. If you want to build your online community, you need to consider all the amazing features you get with WordPress. Plugins such as BB Press is an open-source, template-driven PHP/ MySQL forum software. It is very simple and doesn’t hamper the experience of the website.
Other tools such as wpFoRo and Asgaros Forum are equally good for creating a community blog. They are lightweight tools that are easy to manage and integrate with your WordPress site easily. However, there is only one tiny problem; you need to have some technical knowledge to build a WordPress Community blog page.
Since we gave you a problem in the previous section, we would also give you a perfect solution for it. You might not know to code, but you have shortcodes. Shortcodes help you execute functions without having to code. It is an easy way to build an amazing website, add new features, customize plugins easily. They are short lines of code, and rather than memorizing multiple lines; you can have zero technical knowledge and start building a feature-rich website or application.
There are also plugins like Shortcoder, Shortcodes Ultimate, and the Basics available on WordPress that can be used, and you would not even have to remember the shortcodes.
5. Build Online Stores
If you still think about why to use WordPress, use it to build an online store. You can start selling your goods online and start selling. It is an affordable technology that helps you build a feature-rich eCommerce store with WordPress.
WooCommerce is an extension of WordPress and is one of the most used eCommerce solutions. WooCommerce holds a 28% share of the global market and is one of the best ways to set up an online store. It allows you to build user-friendly and professional online stores and has thousands of free and paid extensions. Moreover as an open-source platform, and you don’t have to pay for the license.
Apart from WooCommerce, there are Easy Digital Downloads, iThemes Exchange, Shopify eCommerce plugin, and so much more available.
6. Security Features
WordPress takes security very seriously. It offers tons of external solutions that help you in safeguarding your WordPress site. While there is no way to ensure 100% security, it provides regular updates with security patches and provides several plugins to help with backups, two-factor authorization, and more.
By choosing hosting providers like WP Engine, you can improve the security of the website. It helps in threat detection, manage patching and updates, and internal security audits for the customers, and so much more.
