my_enum=MyEnum.ENUM_VALUE1 string_value=enum_to_string(my_enum)print(string_value) 1. 2. 3. 上述代码中,我们首先创建了一个MyEnum的实例my_enum,并将其赋值为ENUM_VALUE1。然后,我们调用enum_to_string方法将my_enum转换为字符串,并将结果赋值给string_
Enum string comparison To compare a string with an enum, extend from thestrclass when declaring your enumeration class, e.g.class Color(str, Enum):. You will then be able to compare a string to an enum member using the equality operator==. How to compare a string with an Enum in Pyt...
使用以下 mermaid 语法表示枚举类信息: TrafficLightWithSharedValues+string RED = "STOP"+string YELLOW = "STOP"+string GREEN = "GO" 结语 通过以上步骤和代码示例,你已经掌握了如何在Python的Enum中实现多个成员对应同一值的技巧。这样的设计可以在很多场景中使用,例如处理状态机、日志级别、错误码等场合。希望...
The example fails with theValueError: duplicate values found in <enum 'Season'>: WINTER -> AUTUMNerror, because the AUTUMN and WINTER members have the same value. If we comment out the@uniquedecorator, the example prints three members; the WINTER is ignored. The __members__ attribute The s...

将String 变量转换为 float、int 或 boolean 向字符串填充或添加零的不同方法 去掉字符串中的 space 字符 生成N个字符的随机字符串 以不同的方式反转字符串 将Camel Case 转换为 Snake Case 并更改给定字符串中特定字符的大小写 检查给定的字符串是否是 Python 中的回文字符串 ...
In this example, a list of two-part tuples is given instead of a single string containing only the member names. This makes it possible to reconstruct theBugStatusenumeration with the members in the same order as the version defined inenum_create.py. ...
@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 ...
