Pygame keyboard input issue

Question

I am trying to get user keyboard input using pygame. However, the problem is that after I run my code on IDLE, the keyboard input is never read by the program, and whatever I type is shown on the shell. Same issue if I run my code on PyCharm. Any idea? Below is my code:

pygame.init()
screen = pygame.display.set_mode((800, 600))
running = True
while running:
     for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == KEYDOWN and event.key == pygame.K_w:
            print("Yup!")
     pygame.display.flip()

Why the hack are you running a pygame app in terminal?! pygame is for making games in non-terminal windows! — linusg

Make sure the pygame window has the focus, otherwise your keyboard input will not be recognized! — linusg

It is focused when I run the code, but still same problem..Keyboard input is never read... — lanlan2271

It doesn't work because it can't detect any key pressed on my keyboard. — lanlan2271

I'm having the exact same issue, also on a Mac using Pycharm and python 3.6. I'm printing the events and only MouseMotion events are recorded, rather than KeyDown.

Edit: apparently it's a known issue: Window does not get focus on OS X with Python 3

This is my code, and it also should work:

while not crashed:
for event in pygame.event.get():
    print(event)
    if event.type == pygame.QUIT:
        crashed = True

    # get current list
    pressed = pygame.key.get_pressed()
    if pressed[pygame.K_UP]:
        print("UP")

    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_1:
            print('this DOES work! :)')
        elif event.key == pygame.K_LEFT:
            x_change = -5
        elif event.key == pygame.K_RIGHT:
            x_change = 5
        elif pressed[pygame.K_UP]:
            print("UP")
    if event.type == pygame.KEYUP:
        if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
            x_change = 0

    pygame.display.flip()

x += x_change

gameDisplay.fill(black)
ship(x, y)

pygame.display.update()
clock.tick(60)

This code works perfectly for me

import pygame

pygame.init()
windowSize = width,height = 800,600
screen = pygame.display.set_mode(windowSize)


running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            quit()

        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_w:
                print("Yup!")



    pygame.display.flip()
