Python tkinter includes plugin Types & Variable variables in tkinter

Tkinter is a built-in GUI library for python installation. It is cross-platform. Although it is simple, I have seen many people on the internet saying that it is boring to learn this GUI library. Now there are so many good GUI Libraries, however, I think the existence is reasonable and there is always a reason for learning. I want to use this GUI library to learn simple GUI interface design and Python knowledge about object-oriented programming.

Tkinter includes some small plug-ins, as described below:

Canvas is used to draw or display areas of an image.

The checkbutton clickable box. Its status can be selected or unselected.

Variable in tkinter

Because the strings, integers, floating-point numbers, and boolean values in Python are unchangeable, tkinter comes with some types that can be updated locally and can notify related plug-ins when their values change. The following describes the immutable types in Python and the variable types in tkinter.

Immutable type and variable type

Int intvar

String stringvar

Bool booleanvar

Double doublevar

The variable type value is set and obtained through the set and get methods.
