枚举类

• 枚举类的使用

    #!/usr/bin/env python3
    # -*- coding: UTF-8 -*-
  
    from enum import Enum
  
    MonthEnum = Enum('Month', ('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'))
  
    for name, member in MonthEnum.__members__.items():
        print(name, '-----', member, '------', member.value)
  

• 自定义类型的枚举

    #!/usr/bin/env python3
    # -*- coding: UTF-8 -*-
  
    from enum import Enum, unique
  
    # @unique 装饰器可以帮助我们检查保证没有重复值
    @unique
    class MonthClass(Enum):
        Jan = 'January'
        Feb = 'February'
        Mar = 'March'
        Apr = 'April'
        May = 'May'
        Jun = 'June'
        Jul = 'July'
        Aug = 'August'
        Sep = 'September '
        Oct = 'October'
        Nov = 'November'
        Dec = 'December'
  
    if __name__ == '__main__':
        print(MonthClass.Jan, '----------',
              MonthClass.Jan.name, '----------', MonthClass.Jan.value)
        for name, member in MonthClass.__members__.items():
            print(name, '----------', member, '----------', member.value)
