if __name__ == "__main__":

if __name__ == "__main__"是Python中常见的一个用法。它通常用于判断当前文件是作为主程序运行，还是作为模块被其他程序导入使用。 这个条件语句的作用是，当.py文件被直接运行时，if __name__ == "__main__"之后的代码块将被执行；当.py文件以模块形式被导入时，if __name__ == "__main__"之后的代码块将不会被执行。 这样做的好处是可以在开发过程中对模块进行测试，同时还可以在模块被导入时不执行一些不必要的代码。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
