一、基础操作：5分钟上手Python枚举定义第一个枚举类from enum import EnumclassOrderStatus(Enum): PENDING = 1# 待处理 PROCESSING = 2# 处理中 COMPLETED = 3# 已完成用法示例：current_status = OrderStatus.PROCESSINGprint(current_status.value) # 输出：2print(current_status.name) # 输出...
可以通过enum_ = Enum('class_name', names,start = 1)来创建,其中names可以是字符串,可以是列表/元组。内部定义为: def_create_(cls, class_name, names, *, module=None, qualname=None,type=None, start=1):"""Convenience method to create a new Enum class. `names` can be: * A string conta...
