How can I make it so that something happens in pygame when I type a number

Question

My code is:

keys = pygame.key.get_pressed()
  if keys[pygame.K_1]:
    if money >= worker_cost:
      money -= worker_cost
      workers += 1
      worker_cost = round(worker_cost*1.1, 2)

So I am trying to make a game in pygame, but when I put this in to detect when the user wants to buy something, it won't detect that I pressed anything. I have tried putting print commands inside the if loop to see if the loop starts, but it doesn't. Any tips would be appreciated

there is no loop in your code, have you tried checking if it registers the press at all (put `print` in the `if keys[pygame.K_1]:` block (outer one), maybe the second condition is not met?)? do you call `pygame.event.get()` anywhere in the main loop? it has to be called — Matiiss, Nov 14 '21 at 17:58

Use the keyboard events instead of pygame.key.get_pressed().

pygame.key.get_pressed() returns a list with the state of each key. If a key is held down, the state for the key is True, otherwise False. Use pygame.key.get_pressed() to evaluate the current state of a key and get continuous movement.

The keyboard events (see pygame.event module) occur only once when the state of a key changes. The KEYDOWN event occurs once every time a key is pressed. KEYUP occurs once every time a key is released. Use the keyboard events for a single action:

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

        if event.type == pg.KEYDOWN:
            if event.key == pg.K_1:

                # do action
                if money >= worker_cost:
                    money -= worker_cost
                    workers += 1
                    worker_cost = round(worker_cost*1.1, 2) 

    # [...]
