in the StackOverflow.Roughly doubled: When the Python interpreter reads the py file, it executes all the code it finds. It defines a number of variables before executing the code. For example, if the py file is the main program, it will set the __name__ variable to "__main__" . If this py is introduced to another module, it __name__ will be set to the name of the module.
