Using a module's __name__
Example 8.2. Using a module's __name__
#!/usr/bin/python
# Filename: using_name.py if __name__ == '__main__':
else: print 'This program is being run by itself' print 'I am being imported from another module'
Output
$ python using_name.py
This program is being run by itself $ python
>>> import using_name
I am being imported from another module >>>
How It Works
Every Python module has it's
__name__ defined and if this is
'__main__', it implies that the module is being run standalone by the user and we can do corresponding appropriate actions.
