For this reason, Python 3.11 will include a StrEnum type with direct support for common string operations. In the meantime, you can simulate the behavior of a StrEnum class by creating a mixin class with str and Enum as parent classes. Remove ads Creating Integer Flags: IntFlag and Flag ...

@enum.unique 专用于枚举的 class 装饰器。 它会搜索一个枚举的 __members__ 并收集所找到的任何别名;只要找到任何别名就会引发 ValueError 并附带相关细节信息: >>> >>> from enum import Enum, unique >>> @unique ... class Mistake(Enum): ... ONE = 1 ... TWO = 2 ... THREE = 3 ...

enum 是Python 自 3.4 版本引入的内置模块,如果你使用的是更早的版本,可以通过 pip install enum34 来安装它。下面是使用 enum 的样例代码: # -*- coding: utf-8 -*- from enum import IntEnum class TripSource(IntEnum): FROM_WEBSITE = 11 FROM_IOS_CLIENT = 12 def mark_trip_as_featured(trip):...
object_hook=as_complex)print(result3)#(1+2j)f=open('a.json')# 从文件流恢复JSON列表 result4=json.load(f)print(result4)#['Kotlin',{'Python':'excellent'}] 上面程序开始调用loads()函数从JSON字符串恢复Python列表、Python字符串等。接下来程序示范了一个比较特殊的例子—程序定义了一个自定义的恢...
