if __name__ == '__main__':

[Michael Wieher]

Well, consider this:

you have a file named <mymodule>.py, built like this:
~~~~~~~~~~~~~~~~~~~~~
#!/usr/bin/python

def <function>:
    ....
    return <data>

if __name__=="__main__":
    print "Unit test"
else:
    pass #module imported by another module/script
~~~~~~~~~~~~~~~~~~~~~~

If you type, on command line, >python ./<mymodule>.py
you will see "Unit test" printed to the screen.

if, however you are in another python file and type "import <mymodule>" the
code will, instead, "pass" and nothing will occur.

I hope this helps =)
