if __name__ ==“＿＿main__”

if __name__ == "__main__"是Python中常见的一句代码，它在脚本文件中起到一个特殊的作用。当脚本文件直接被执行时，也就是作为主程序运行时，if __name__ == "__main__"后的代码块会被执行。而当脚本文件作为一个模块被导入时，if __name__ == "__main__"后的代码块则不会被执行。通过这种方式，可以使某些代码只在脚本文件被直接执行时运行，而在作为模块被导入时不运行。这样可以方便进行测试和模块的复用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
