您是python的新手并尝试在脚本下运行并获取属性错误。

 #!/usr/bin/python

并且出现打击错误 Traceback（最近一次调用最后一次）：文件“./pyth.py”，第136行，in 主要（）在主文件中输入“./pyth.py”，第44行如果不是（args.username和args.password）： AttributeError：'Namespace'对象没有属性'username'

Answer 1

您尚未在ArgumentParser中定义print("Winners are:\n{}".format("\n".join(names))参数。你定义了一个名为username的东西，你的意思是改用它吗？

AttributeError - Namespace对象没有属性username
