I have a Python-3 application that has an interactive command-line interface. Now I would like to add non-canonical keyboard input functionality to this application. I would like it to behave much like how Python interpreter handles its keyboard inputs - for example, keys like up-arrow and down-arrow could scroll command histories and other control keys could move the cursor to beginning/end of line, etc.

I had a cursory glance of getkey and keyboard modules, but what is the best (and easiest) Python 3 module that I could use for this feature?

  • there are special modules for command line - even IPython use one of them - Python Prompt Toolkit. Even standard module cmd should have some of this functions. Most of them use modul readline for this. Commented Mar 4, 2020 at 2:50

There are special modules to create interactive command line.

They can use special keys to show history, edit line, auto suggestions.

There is standard module cmd which should have this functionality.

Probably the most popular is Python Prompt Toolkit. Probably even IPython uses it.

See Gallery, basic tutorila and examples with PtPython

Probably most of them use standard modul readline - so maybe you will need this for your project.
