Tkinter in Python 2.x
In 2008, Guido van Rossum, the author of Python, forked the language into two branches—2.x and 3.x. This was done to clean up and make the language more consistent.
Python 3.x broke backward compatibility with Python 2.x. For example, the print statement in Python 2.x was replaced by the print() function that would now take arguments as parameters.
We coded all the Tkinter programs in Python version 3.x. However, in case you need to maintain or write new Tkinter programs in Python 2.x, the transition should not be very difficult.
The core functionality of Tkinter remains the same between 2.x and 3.x. The only significant change to Tkinter when moving from Python 2.x to Python 3.x involves changing the way the Tkinter modules are imported.
Tkinter has been renamed to tkinter in Python 3.x (capitalization has been removed). Note that in 3.x, the lib-tk directory was renamed to tkinter. Inside this directory, the Tkinter.py file was renamed to __init__.py, thus making...
