This is a game function from pygame. If user press left (pygame.KEYDOWN.K_LEFT), angle -= 1. Else if user press right (pygame.KEYDOWN.K_RIGHT), angle += 1. 'Event.type' is the detection of which key the user pressed. angle can be negative.

Question: is this a recursive approach? if yes, how to change it to be iterative, or faster efficiency?

angle = 0
if event.type == pygame.KEYDOWN.K_LEFT:
    angle -= 1 
elif event.type == pygame.KEYDOWN.K_RIGHT:
    angle += 1

Could you share the whole code? I don't see any recursive approach in this part. – Amir Sabzehparvar May 06 '22 at 15:50
*"is this a recursive approach?"* - No. A recursion is `def foo(i): ... foo(i+1) ...` – Rabbid76 May 06 '22 at 16:00
