[python] Python main call within class

I haven't done much python - coming from a C/Java background - so excuse me for asking such a simple question. I am using Pydev in Eclipse to write this simple program, and all I want it to do is to execute my main function:

class Example():

if __name__ == '__main__':
    Example().main()        <----- What goes here?


    def main(self):     
        print "Hello World!

That is what I have now. I have also tried

self.main() 

and

main()

and

main(self)

none of which work. What am I missing?

Remember, you are NOT allowed to do this.

class foo():
    def print_hello(self):
        print("Hello")       # This next line will produce an ERROR!
    self.print_hello()       # <---- it calls a class function, inside a class,
                             # but outside a class function. Not allowed.

You must call a class function from either outside the class, or from within a function in that class.

That entire block is misplaced.

class Example(object):
    def main(self):     
        print "Hello World!"

if __name__ == '__main__':
    Example().main()

But you really shouldn't be using a class just to run your main code.
