if __name__ == '__main__':

if __name__ == '__main__'是一个常见的Python编程语句。它的作用是判断当前模块是否是直接被运行还是被导入到其他模块中。如果当前模块是直接被运行的，即作为主程序执行，那么if __name__ == '__main__'之后的代码块将被执行。而如果当前模块是被导入到其他模块中的，那么if __name__ == '__main__'之后的代码块将不会被执行。这一语句的作用是为了避免在导入模块时执行一些不必要的代码，只在模块作为主程序执行时才执行特定的代码块。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
