Python 3.9: if __name__ == '__main__'
Welcome to another Python 3.9 tutorial video, this video is about __name__.
So lets look at it,
Before executing code, Python interpreter reads source file and define few special variables/global variables.
If the python interpreter is running that module (the source file) as the main program, it sets the special _name_ variable to have a value “__main__”. If this file is being imported from another module, _name_ will be set to the module’s name.
