how to keep trigering a pygame event as long as a key is pressed

Question

i am creating a clone of chrome dino game and when i press the space button the player jumps but when it comes down and touches the ground i does not jumps automatically even if the key is still pressed i want it to jump automatically if the key still pressed the necassary code is below if someone wants the full code tell me and also i want a to add a pause menu in the game so can someone tell me function similar to time.sleep() except instead of delaying the progam upto given number of second it dealys the program till a certain condition is true or something like that or i'll have to do it manually

class player(pygame.sprite.Sprite):
        def __init__(self, position):
            pygame.sprite.Sprite.__init__(self)
            # settings

Use pygame.key.get_pressed() instead of the pygame.KEYDOWN event. pygame.key.get_pressed() returns a sequence with the state of each key. If a key is held down, the state for the key is 1, otherwise 0. e.g.:

while True:
    # [...]

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()
        # DELETE
        #if event.type == pygame.KEYDOWN:
        #    if event.key == pygame.K_SPACE and alien.allow_jump:
        #        alien.velocity = -17
        if event.type == pygame.MOUSEBUTTONDOWN:
            if alien.rect.collidepoint(event.pos) and alien.allow_jump:
                alien.velocity = -18

    keys = pygame.key.get_pressed()
    if keys[pygame.K_SPACE] and alien.allow_jump:
        alien.velocity = -18
        alien.allow_jump = False

    # [...]
