[Resending because I messed up on last email] My question was regarding a piece of boilerplate code:
if __name__ == '__main__': main() This calls the main function, but I don't understand what the 'if' statement is doing here. In the simple programs that I've seen this so far, there is no variable called "_name_", and even if there was, why is it comparing it to "_main_"? Why can't the main function just be called by typing main()- why do we need this if statement to precede it? Thanks. -Alex On Thu, Jun 14, 2012 at 3:17 PM, Alexander Quest <alexxqu...@gmail.com>wrote: > Got it Dave- sorry about not sending it to the newsgroup as well. > > My question was regarding a piece of boilerplate code: > > > if __name__ == '__main__': > main() > > This calls the main function, but I don't understand what the 'if' > statement is doing here.
