Creating GUI applications in Python using TKinter by Oleksa Kushnir

If you want to create a GUI application in Python you can use TKinter. It's a standard open-source python framework - a thin object-oriented layer on top of the Tk toolkit.

The TK toolkit is a cross-platform collection of ‘graphical control elements’, aka widgets, for building application interfaces. So you can use the same code for different OS and expect that your application will be working the same way.

This topic covers basic usage of the TKinter framework:
