Example 2: what is __name__ == "__main__":
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. If you import this script as a module in another script, the __name__ is set to the name of the script/module.
