When trying to blit a background in pygame, I get this error message

Question

I'm new to pygame as of yesterday, and I keep running into this issue when trying to blit anything onto the screen. I am running mac osx 10.6.8. I am writing it all out in textwrangler, and executing it in the terminal with python2.7-32 filename.py

Traceback (most recent call last):
  File "adventure.py", line 35, in <module>
    screen.blit(background(0, 0))
TypeError: 'pygame.Surface' object is not callable

Here is my python program

Answer 1

Try changing screen.blit(background(0, 0)) to screen.blit(background,(0, 0)) (without the comma, you are treating background as a function/callable instead of as a parameter. Think of it like calling a function named background with the argument (0, 0).). screen.blit's two required arguments are a source and a destination, so putting a comma after background supplies both arguments (source is background, destination is (0, 0)).
