Pygame 'LEFT' is not defined
Question: I'm working on a game. I have pygame imported. I am using Python 3.3 and
Pygame 3.3. The same error message all the time "LEFT" is not defined. I did
exact copies of what were on the internet as I already did a search for the
problem. Here is my code. I have tried a few different ways and neither seem
to work.

method 1:

    
    
    import pygame
    event = pygame.event.poll()
    if event.type == pygame.MOUSEBUTTONDOWN and event.button == LEFT:
        ....command
    

method 2: (basically going all in)

    
    
    from pygame import *
    from pygame.locals import *
    import pygame
    event = pygame.event.poll()
    if event.type == MOUSEBUTTONDOWN and event.button == LEFT:
        ......command
    

Before telling me, on both those methods I tried switching between "LEFT" and
"pygame.LEFT", and so on.

Any ideas?

Hugely appreciated.


Answer: Define `LEFT` yourself:

    
    
    LEFT = 1
    

The [Pygame tutorial](http://lorenzod8n.wordpress.com/2007/05/30/pygame-
tutorial-3-mouse-events/) I think you are following does exactly that. In
other words, the `pygame` library has no constants for this value, it's just
an integer.
