Understanding if __name__ == “__main__” in Python | Python Main Function with Examples
Показать описание
In this Python Tutorial for Beginners video I am going to show you the Idea behind using : if __name__ == "__main__" in Python. __name__ is a built in variable in Python. the value of __name__ is set to "__main__" at runtime. Each module has a name, and this name can be used to access instructions in a module. This is especially useful in a given situation: As mentioned before, the main block of a module is executed when it is imported for the first time. But what do we do if we want the block to run only if the module was started as a stand-alone program, but not if it was imported from another module? We can do this by evaluating the attribute __name__ of the module.
