#2 Created at ... [Delete] [Delete and Lock User]

额 在github文件页点raw，然后在raw里复制代码再粘贴就没事了。。应该是直接在文件页里复制代码会有问题吧。。。

#3 Created at ... [Delete] [Delete and Lock User]

不过，还想问下的是，测试通过是输出"."吗？

#4 Created at ... [Delete] [Delete and Lock User]

根据你的错误提示：

TypeError: descriptor '__init__' of 'super' object needs an argument

是你自己定义的Dict类的init函数中除了self参数，还有另外一个参数，类似这样,注意最后那个括号里：

super(Dict, self).__init__(arg)

应该改成：

super(Dict, self).__init__()

因为init类似c++中的构造函数，在调用时会自动执行，而你没有传入任何参数
