Turtle not detecting key presses in Python [duplicate]

Question

Here is a HUGELY simplified version of my code:

from turtle import Turtle, Screen
import time

speed_x = 20
speed_y = 29

def move_right():
    print('exectuted')
def game_loop():
    ball.goto(ball.xcor() + speed_x, ball.ycor() + speed_y)

    window.update()

    window.ontimer(game_loop, 1)


window = Screen()
time.sleep(2)

ball = Turtle(shape='circle')
ball.color('white')


paddle = Turtle(shape='square')

window.onkeypress(move_right, 'Right')
window.onkeypress(move_right, 'D')

game_loop()

window.mainloop()

I expected the move_right() function to execute (which for testing should have printed out something)

But I get nothing

Answer 1

I would consider adding window.listen() before setting up the key bindings for the move_right()

window.listen()
window.onkeypress(move_right, 'Right')
