Hi Gurus,

if __name__ == '__main__':

-Ganesh
If you execute the script directly ie. python script.py the __name__
will be __main__ but if you import it it's the name of the file.
#first.py
print __name__
#second.py
import first
$ python first.py
__main__
$ python second.py
first
Sorry, forgot to add before sending that the reason I use the `if
__name__ == '__main__'` structure is so that I can have a standalone
application that has it's defined entry point and then if I want to
reuse functions in the application I can import it without having to
worry that it will execute the entire thing.
