python - Getting Pygame keyboard input and check if it's a number

Question

I am trying to get keyboard input using Pygame using this command:

if event.type == pg.KEYDOWN:
    # ADD KEYBOARD EVENTS
    keys = pg.key.get_pressed()

I want to check if the button pressed represents a number, I already know how to check if a string represent a number using try/except command, but, in my code keys is not a string, it is a huge tuple - and I don't know how to get it in an efficient way because every time I look in the internet on how to get keyboard input, they need to equate keys to something like pygame.pygame.K_LEFT and I don't want to do this for each number and furthermore every number in the number-pad (right side).

Is there an efficient way to determine if a user clicked on a number? Thanks!

Answer 1

pygame.key.get_pressed() returns a list with the state of all keyboard buttons. This is not intended to get the key of a keyboard event. The key that was pressed can be obtained from the key attribute of the pygame.event.Event object:

if event.type == pg.KEYDOWN:
    if event.key == pg.K_a:
        # [...] 

unicode contains a single character string that is the fully translated character:

if event.type == pg.KEYDOWN:
    if event.unicode == 'a':
        # [...]
