Python source code

 

When a Python file is run directly, the special variable "__name__" is set to "__main__". 

 

There is hello.py file as follows:

 

import sysdef main():    print 'Hello,', sys.argv[1]if __name__ == '__main__':    main()

We can run in the IPyhton:

run hello.py Michael

 

And the result is:

Hello, Michael
