是Enum是类，Month是Enum的实例吗？ 还是Month是类，各个枚举值是Month的实例？

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

有空的话自己试一下：

type(Enum)
type(Month)
isinstance(Month.Jan, Month)
isinstance(Month.Jan, Enum)

请问廖老师，Enum和Month都是class，但又不属于Month继承Enum的class吧？

type(Enum)

<class 'enum.EnumMeta'> type(Month)

<class 'enum.EnumMeta'> isinstance(Month.Jan, Month) True isinstance(Month.Jan, Enum) True isinstance(Enum, Month) False isinstance(Month, Enum) False

Enum和Month都是类

Month继承Enum

各个枚举值是Month的实例

同时也是Enum的

这个是正解！

#8 Created at ... [Delete] [Delete and Lock User] 
Month = Enum('Month',('Jan','Feb','Mar','Apr',
                      'May','Jun','Jul','Aug',
                      'Sep','Oct','Nov','Dec'))

我还以为是强制转换呢。。。是不是强制转换呢？？？

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

不是强制转换，python的类可以动态创建，这里是返回了新的class

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

for value in weekday.members.values(): print(value)

weekday.sun weekday.mon weekday.tue weekday.wed weekday.thu weekday.fri weekday.sat

为什么返回的 不是 赋值的数字呢
