dict全称为dictionary,是python的内置字典。使用 key-value 键值对存储,一个key只对应一个value。类似 java 中的 map,使用了哈希表的数据结构,有极快的查找速度。使用方法如下: >>> dict = {'a':100,'b':200,'c':300}>>> dict['c']#根据key获取value300 >>> dict['Adam'] = 400#通过key放入value...
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...
从int类型转为枚举类型: using System; namespace 类型转换 { public enum QQState { OnLine, OffLine, Leave, Busy, QMe } class Program { static void Main(string[] args) { int n1 = 0; QQState state = (QQState)n1; Console.WriteLine(state); Console.ReadKey(); } } } 运行结果: OnLine ...
