原因很简单,因为if __name__ == '__main__'中的__name__代表的就是当前执行的模块名。 python一切皆对象,所以python的模块也是对象,他有一个 built-in module,叫__name__,存储着模块是如何被执行的,如果是执行当前模块,那么就显示__main__,如果是被引用进来的,就显示被引用的路径。 好了,解释完了这个...
筛选args中值(value)为True的键值(Key) commands = [key for key in args.keys() if args[key] == True] 这行是利用Python的语言特性——列表解析式(list comprehension),将args这个字典里value为True的key都筛选出来。接下来要做的就是构建用来取代if-else statements的字典对象: 取代if-else的字典 前面为什...
