1)将字符串全体小写。 2.casefold与lower用法 string.casefold(),也就是说:调用字符串的casefold函数,并且函数的()内什么都不用填写,因为它没有参数,不需要传。 casefold会生成一个新的字符串,并且可以把这个新的字符串赋值给一个新的变量,也就是newstr。 lower的用法和casefold是一样
string.casefold官方说明: Casefolding is similar to lowercasing but more aggressive because it is intended to remove all case distinctions in a string. For example, the German lowercase letter'ß'is equivalent to"ss". Since it is already lowercase,lower()would do nothing to'ß';casefold()c...
python 3.3 引入了string.casefold 方法,其效果和 string.lower 非常类似,都可以把字符串变成小写,那么它们之间有什么区别?什么时候该用string.casefold而非string.lower?? In [5]: name = 'Xu Zhoufeng' In [6]: name.casefold() Out[6]: 'xu zhoufeng' In [7]: cname = 'Yu Dongfeng' In [8]: cn...

在Python 的官方文档中 Python 文档非常清楚这就是各个方法的作用,它们甚至将用户指向前面提到的第 3.13 节。 他们将 .lower() 描述为将大小写字符转换为小写字符,其中大小写字符是 “具有一般类别属性为“Lu”(大写字母)、“Ll”(小写字母)或“Lt”之一的字符“(字母,标题)” 。与 .upper() 和大写相同。
以上示例中,最后的输出结果都是'i love python'。 那么这两个函数有什么区别呢? 首先想到的是,查看帮助,使用help方法: >>>help(str.lower) Help on method_descriptor: lower(...) S.lower()->str Return a copy of the string S converted to lowercase.>>>help(str.casefold) ...
Python String casefold()用法及代码示例 casefold() 方法是一种激进的lower() 方法,它将字符串转换为大小写折叠字符串以进行无大小写匹配。 casefold()方法删除string中存在的所有大小写区别。它用于无大小写匹配,即在比较时忽略大小写。 例如,德语小写字母ß等价于ss。但是,由于ß已经是小写字母,因此lower()...
