Pygame does not detect Mouse presses

Question

I am building a simple python script that runs functions that control the Unicorn HAT on the RPi. My Intention is to control this using mouse clicks.

while True:
    for event in pygame.event.get()
        print(event)
        if event.type == pygame.MOUSEBUTTONDOWN:
            if event.button == 1:
                if upRun or tRun == 1: #Cancel any scrollers
                    upRun = 0
                    tRun = 0
                n()
            elif event.button == 2:
                up()
            else:
                art()

On testing this I receive no output. Note I have called pygame.init() as required.

Polling all events results only in empty events.

Is this the way the indentation in your code looks? Because the indentation in your for loop is incorrect — C_Z_
Well catched. Yes the indentation is different, it currently runs fine. — Iceblue
Did you remember to set up display properties? If not, that's probably why (no display, no events) — jDo
Thanks jDo. Having tried that earlier to no success I ruled that out, but works now. — Iceblue

Something tells me that you didn't set up any display properties. I could be wrong but this works for me:

import pygame

pygame.init()
screen = pygame.display.set_mode((800,600))

while True:
    for event in pygame.event.get():
        print(event)
        if event.type == pygame.MOUSEBUTTONDOWN:
            if event.button == 1:
                if upRun or tRun == 1: #Cancel any scrollers
                    upRun = 0
                    tRun = 0
                n()
            elif event.button == 2:
                up()
            else:
                art()
