Python python turtle graphics window not responding

[TiffanyWart]

[CODE lang="python" title="This code works"]import turtle
player=turtle.Turtle()
def space():
print("spacebar pressed")
turtle.onkeypress(space, "space")
turtle.listen()[/CODE]
[CODE lang="python" title="This code doesn't work" highlight="7-8"]import turtle
player=turtle.Turtle()
def space():
print("spacebar pressed")
turtle.onkeypress(space, "space")
turtle.listen()
while True:
a=1[/CODE]
When I have no while loop the code works and everytime i press spacebar it'll print "spacebar pressed"
When I do have a while loop the code doesn't work and the turtle graphics window doesn't respond.
Why doesn't it work when I have the while loop? How can I fix this issue?

Looks like you need to at least put the turtle.listen() in the while loop.
OR
There is no condition which exits the while loop - you should add something to the while loop so that it exits.

Hi @TiffanyWart,

Did you try the solution @Krusty the Senile provided?

Hi @TiffanyWart,

Yes. Putting the listen command inside the while loop doesn't work. It doesn't seem the turtle module on python doesn't like while loops with events. I found someone having the same problem here and while trying things I found out that if you put something that has to do with the screen the problem is fixed:
[CODE lang="python" title="This code works" highlight="10-11"]import turtle
pen=turtle.Turtle()
def space():
print("spacebar pressed")
turtle.onkeypress(space, "space")
turtle.listen()
pen.hideturtle()
pen.penup()
while True:
pen.goto(-100,100)
pen.goto(100,-100)[/CODE]
Putting a way to exit the loop does work, but only after the loop is finished. Imagine I press the spacebar 8 times while the while loop is going, then when the while loop finishes, it prints "spacebar pressed" 8 times. The same thing happens with a for loop. Well at least I found a fix, but I still don't know why the turtle module acts with way.
