I've just posted guides for running Python tkinter programs on Android in the Pydroid 3 app's IDE. The first covers multiple programs, and the second focuses on a content-sync program: https://learning-python.com/using-tkinter-programs-on-android.html https://learning-python.com/mergeall-android-scripts/_README.html And yes, you read that right: Python tkinter GUIs, including the calendar, calculator, text editor, and incremental backup tool described in these docs, now work on your smartphone in addition to your PC, though they come with a few rough edges (and advertising) on Android today. And there was much rejoicing, --M. Lutz (http://learning-python.com)
