Month = Enum('Month', ('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'))
for name, member in Month.__members__.items():
    print(name, '=>', member, ',', member.value)

这里用到的Month其实不是非得一样，我改成

s = Enum('r', ('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'))
for name, member in s.__members__.items():
    print(name, '=>', member, ',', member.value)

然后，看

from enum import Enum, unique

@unique
class Weekday(Enum):
    Sun = 0
    Mon = 1
    Tue = 2
    Wed = 3
    Thu = 4
    Fri = 5
    Sat = 6
for name, member in Weekday.__members__.items():
    print(name, '=>', member)

这里Weekday既充当了s（Weekday.__members__.items()类似s.__members__.items()）也充当了r（打出的member，一个是Weekday.Sun这种，一个是r.JAN这种），Weekday应该是枚举类，那s和r又分别是什么呢？
