There is also prompt_toolkit[1] for even more fancy command‐line 
handling. The documentation even states it “can be a very advanced pure 
Python replacement for GNU readline, but it can also be used for 
building full screen applications.” (It doesn’t depend on readline or 
libedit.) It’s used by IPython for its history, editing, and completion 
features. If cmd with readline is overkill for your use case then this 
is even more so, but I thought it worth a mention.
