from enum import Enum,unique

###定义及使用枚举：方式一###
@unique #@unique装饰器可以帮助我们检查保证没有重复值
class Weekday(Enum):
    Sun = 0  # Sun的value被设定为0
    Mon = 1
    Tue = 2
    Wed = 3
    Thu = 4
    Fri = 5
    Sat = 6

print(Weekday.Fri) #output "Weekday.Fri"
print(Weekday.Fri.value) #output "5"
print(Weekday(1)) #output "Weekday.Mon"
print(Weekday(1) == Weekday.Mon) #output "True"
print(Weekday.Sun == Weekday.Mon) #output "False"
