I guess, quite often, you see the usage of __name__ in Python. Yes, it is a keyword (attribute) associate to a module. It can be used to tell if the module is being run as stand-alone by the user.
#!/usr/bin/env python
if __name__ == "__main__":
print "standalone"
else:
print "imported", __name__
Save this as test.py and press F5 in the IDLE, you will have the “standalone” printed.
In the IDLE, type in import test, you will have “imported test” printed.
[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.]
Experiments directly under the Python shell are shown below.
>>> __name__ "__main__" >>> test.__name__ "test" >>>
