The easiest Python method is probably input():

    direction = input("Which direction, x or y? ")

followed by an if-construct to call either forward_step() or
backward_step().

Some ideas: https://pynative.com/python-input-function-get-user-input/

You may prefer pygame or something similar (https://www.pygame.org/news)
which facilitate both mouse and keyboard interrogation - and in a
fashion which may be familiar to robot-control.

More complicated is the Curses library:
https://docs.python.org/3/howto/curses.html which is terminal-oriented.

The above page also mentions libraries which enable "cursor-addressable
text output and full support for mouse and keyboard input." - in case
the "click on" means that you want mouse-control.

Finally, there are GUIs such as tkinter and Qt...
