[FIXED] pausing/ Unpausing in Pygame

Issue

This is the part of mine snake game code that I'm trying to change so I can pause, I'm managing to pause with it, but I'm failing in unpausing(the game freezes), I'm trying to use the key p to pause and u to unpause(the previous keys are for movement and quitting, they function as intended). Any way to do that without freezing? Also, any explanation on why it's not working now is welcomed.

while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                quiting()
            elif event.type == pygame.KEYDOWN:
                # Choose direction by user input, block opposite directions
                key_right = event.key in (pygame.K_RIGHT, pygame.K_d)
                key_left = event.key in (pygame.K_LEFT, pygame.K_a)
                key_down = event.key in (pygame.K_DOWN, pygame.K_s)
                key_up = event.key in (pygame.K_UP, pygame.K_w)
                if key_right and direction != "L":
                    direction = "R"
                elif key_left and direction != "R":
                    direction = "L"
                elif key_down and direction != "U":
                    direction = "D"
                elif key_up and direction != "D":
                    direction = "U"
                elif event.key == pygame.K_ESCAPE:
                    quiting()  # It will quit when esc is pressed
                while event.key == pygame.K_p: # Pausing
                    if event.key == pygame.K_u:  # Unpausing
                        break

Solution

Don't use while but variable paused = True to control functions which move object

paused = False

while True:

    for event in pygame.event.get()

          if event.key == pygame.K_p: # Pausing
              paused = True
          if event.key == pygame.K_u:  # Unpausing
              paused = False

    if not paused:
        player.move()
        enemy.move()

If you want to use one key to pause/unpause

    if event.key == pygame.K_p: # Pausing/Unpausing
        paused = not paused
