Listen for key events in a CLI app

I have a Python program like this:
done = False
while u and not done:
i = u.pop()
print(f"Processing {i}")
do_big_task(i)
finish_up()
Since this takes a long time, the user might get tired of waiting. I want the program to also continually listen for a keystroke, such as space, and if the user presses this done will be set to True so that the loop will automatically stop at the next iteration.
Note that I still want finish_up() to run even if the loop is terminated early.
How can I do this?
