- I have a Python program like this:
- ```python
- 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.- How can I do this?

- Note that I still want `finish_up()` to run even if the loop is terminated early.

Listen for key events in a CLI app
I have a Python program like this:
```python
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.
How can I do this?
