返回一个字符串,其中所有字符均为小写。 lower() 方法只对ASCII编码,也就是‘A-Z’有效,对于其他语言(非汉语或英文)中把大写转换为小写的情况只能用 casefold() 方法。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 S1="Python EXAMPLE...WOW!!!"# 英文S2="ß"# 德语print(S1.casefold())print...

字符串| S.method() Python中的字符串用单引号(')或双引号(")括起来,同时使用反斜杠(\)转义特殊字符。下面总结一下字符串类型的常用方法。 使用格式为:String.method() 1.isalnum():如果字符串至少有一个字符,并且所有字符都是字母或数字则返回True,否则False。
This is a str method in Python 3, but in Python 2, you'll want to look at the PyICU or py2casefold - several answers address this here .这是Python 3中的str方法,但是在Python 2中,您需要查看PyICU或py2casefold- 几个答案在这里解决 。

The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' 连接任意数量的字符串。 调用其方法的字符串被插入到每个给定字符串之间。

The default casefolding can be overridden with a user-defined casefold method. Functionality can be added using mixin classes: HashableMixin mixin class: Adds case-insensitive hashability. KeyableByMixin mixin generator function: Adds ability to get the key from an attribute of the value object. ...
