How to break a core.wait() call

Coding

Hi everyone !

I’m new to psychopy, and I’m struggling to break a core.wait() call.
More precisely, I call the function core.wait() for a bunch of seconds in order to let participant to enter some text. But I would like that, when participant press 'enter', the core.wait() function be deactivated.

Here is an equivalent to what I attempt to do, given what I have understood:

answer_screen.draw()
win.flip(clearBuffer=True)
core.wait(waiting_time)
keys = keyboard.getKeys()
for this_let_key in keys:  
    if this_let_key.name=='return': 
        waiting_time=0
        break
    else:
        print(this_let_key.name)

As I understand it, this does not work because I first ask to wait before entering the for loop. Hence, waiting_time=0 is useless.
However, if I try to put the third line : core.wait(waiting_time) after the for loop, keys pressed are not print for some reason that I do not get.

If anyone could help me to get away with this, it would be of great help !

Hi!

so long as timing is not important I think you instead want event.waitKeys(keyList = 'enter')

Thanks a lot for your answer, it did help me a lot !
I did find a way around thanks to your advice, putting keyboard.waitKeys() in a while loop that would break when 'return' is pressed.
