python 如何防止模块代码从模块执行?

How to prevent modules code execution from module in python?

你不能，当你导入一个模块时，它会运行在全局范围内调用的所有东西.

You can't, when you import a module, it runs everything that is called in the global scope.

您可以更改它以便轻松调用或不调用:

You can change it so that it's easy to call or not:

def main():
    Fu().baz()

if __name__ == '__main__':
    main()

然后当你想要调用它时，你导入它并调用 main() 并且当你将它作为主模块运行时它仍然会自动运行.

And then when you want it called you import it and call main() and it will still automatically run when you run it as the main module.
