GUI with Tkinter in Python

In your project development, you may compose a code and run it in a command-line terminal or an IDE, and the code creates an output based upon what you expect out of it either on the terminal or on the IDE itself. Nevertheless, you maybe want your system to have an elegant looking user-interface, or perhaps your application (use-case) requires you to have a GUI.

GUI is nothing but a desktop app that provides you with a user interface that helps you to connect with the computer systems and enriches your experience of giving a command to your code. They are applied to perform different jobs on desktops, laptops, and other electronic gadgets, etc.

Python has a great deal of GUI frameworks, but Tkinter is the only one that's developed into the Python standard library. It has several strengths. And it's cross-platform so that the exact same code works on Windows, macOS, and Linux. Visual aspects are rendered using native operating system aspects, so applications built with Tkinter look like they belong on the platform where they're run.

Tkinter frequently comes bundled with Python, utilizing Tk, and is Python's basic GUI framework. GUI framework is well-known due to its simplicity and graphical user interface. It is open-source and offered under the Python License. Tkinter offers many controls, like buttons, labels, and text boxes utilized in a GUI application. These useful controls are frequently called widgets.

Although Tkinter is thinking about the de-facto Python GUI structure, it's not without criticism. One significant criticism is that GUIs constructed with Tkinter appearance dated. If you desire a glossy, modern-day interface, then Tkinter may not be what you're looking for.

Nevertheless, Tkinter is lightweight and relatively pain-free to utilize compared to other structures. This makes it an engaging choice for developing GUI applications in Python, particularly for applications where a modern shine is unnecessary, and the top concern is to construct something that's functional and cross-platform rapidly.

There are several techniques utilized that the user requires to remember while creating the Python application with GUI.

1. Tk(screenName=None, baseName=None, className='Tk', useTk=1). It is used to create the main window. You can change the className to the desired one if you want to change the name of the window.

2. mainloop(). It is an infinite loop used to run the application, wait for an event to occur, and process the event as long as the window is not closed.

3. pack(). It is used to organize the widgets in blocks before placing them in the parent widget.

4. grid(). It is used to organize the widgets in the grid (table-like structure) before placing them in the parent widget.

5. place(). It is used to organize the widgets by placing them in specific positions directed by the programmer.
