Introducing Tkinter and Tk
The Tk widget library originates from the Tool Command Language (Tcl)
programming language. Tcl and Tk were created by John Ousterhout while he was
a professor at Berkeley in the late 1980s as an easier way to program the engineering
tools being used at the university. Because of its speed and relative simplicity, Tcl/
Tk rapidly grew in popularity among academic, engineering, and Unix programmers.
Much like Python itself, Tcl/Tk originated on the Unix platform and only later
migrated to macOS and Windows. Tk's practical intent and Unix roots still inform its
design today, and its simplicity compared to other toolkits is still a major strength.
Tkinter is a Python interface to the Tk GUI library and has been a part of the Python
standard library since 1994 with the release of Python version 1.1, making it the de
facto GUI library for Python. Documentation for Tkinter, along with links for further
study, can be found in the standard library documentation at https://docs.python.

Choosing Tkinter
Python coders who want to build a GUI have several toolkit options to choose from;
unfortunately, Tkinter is often maligned or ignored as a legacy option. To be fair, it's
not a glamorous technology that you can describe in trendy buzzwords and glowing
hype. However, Tkinter is not only adequate for a wide variety of applications but
also has some advantages that can't be ignored:
