Why use PySimpleGUI: Python ships with the Tkinter library for creating GUIs, but Tkinter is not known for being easy to work with. PySimpleGUI wraps Tkinter with APIs that are far less exasperating.

Tkinter is a standard GUI library for Python, and it is the most popular Python GUI framework. It is fast, easy-to-use, and provides a wide range of widgets, including buttons, labels, and text boxes.
