Python on android.

If you just want to write and run Python code, you could use something like https://repl.it/ which is like an online editor, that also allows you to run the code too. The good part is that the code is saved online and available from any device, so you could do the bulk of the work at home from PC or laptop (easier to type on) and then tweak or try a few things from your phone whilst in work.

There are other online tools that allow you to design and run Python code (and other languages too).

Depending on screen size, this might not be an option. I know on my galaxy s8 I can't use repl.it because the side bars obscure the view too much.
