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

Dict已经继承了dict的属性，为什么还要用 def init(self, kw): super().init(kw)

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

为了初始化时传参？虽说继承了dict的属性，但是dict的init还是要传值的，所有才有**kw

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

其实是没有必要的

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

**kw是必要的，如果没有它，执行类似于d = Dict(a=1, b='test')这样的语句就会出现问题。而a=1就是关键字参数。如果连可变参数也要传，还要加上*arg。也就是:__init__(self, *arg, **kw)

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

**kw是关键字参数，用于字典。
