: I am just wondering what an "if" statement is. If you know please explain it to me and give me and example of one. Thanks a lot.
This is about as fundamental as you can get. I'm talking PRE first-semester programming here.
if __name__ == '__main__':
In this case, I'm saying "if the value of __name__ is equal to the string '__main__' then print out the string 'foo!'.
