Is pygame module, 'pygame.event.get()' not work on method?

Question

I made a game and used pygame module as the keyboard input. however, it does not seem to respond. there is no error, but my keypress does nothing when I run the code.

I tried using pygame.key but it does not work.

I have no idea what is wrong with this code.

import pygame

pygame.init()


class keypress():
    def check(self):
        for event in pygame.event.get():
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.KEYDOWN:
                    print("Hey, you pressed the key, '0'!")
                if event.key == pygame.K_1:
                    print("Doing whatever")
                else:
                    pass


a = keypress()


if __name__ == "__main__":
    while True:
        a.check()

When I press keys, it does basically nothing.

Pygame will not work without a screen/window defined.

With a window opened, and a couple of minor bugs in the input-handling fixed ~

• event.key needs to check for pygame.K_0, not KEYDOWN again
• Indentation is weird in main loop.
• There's (still) no way to exit

It works mostly how the code seems to describe:

import pygame
pygame.init()
WINDOW_WIDTH = 400
WINDOW_HEIGHT= 400
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))

class keypress():
    def check(self):
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                # TODO - handle exiting
                pass
            elif event.type == pygame.KEYDOWN:
                if event.key == pygame.K_0:
                    print("Hey, you pressed the key, '0'!")
                elif event.key == pygame.K_1:
                    print("Doing whatever")


a = keypress()
if __name__ == "__main__":
    while True:
        a.check()
