The limitations of Tkinter
We have already explored the power of Tkinter. Perhaps the greatest power of Tkinter lies in its ease of use and a lightweight footprint. Tkinter exposes a very powerful API, specially with the Text widget and the Canvas widget.
However, ease of use and the quality of being lightweight that are offered by Tkinter also result in some limitations.
