casefold在python中的用法casefold在Python中的用法 1. 简介 在Python中,字符串是不可变的序列,而字符串方法是用于处理和操作字符串的一组函数。其中之一就是casefold()方法。casefold()方法可以将字符串转换为小写,并且能够处理特殊字符和多语言字符。 本文将详细介绍casefold()方法的功能、用法以及示例,并结合实际场景...
The casefolding algorithm is described in section 3.13 of the Unicode Standard.New in version 3.3.可能是版本问题吧,我的Python2.7.17也是不可以。python里字符串没有这个方法,可以用a.lower()print a.lower()
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...
Return a copy of the string with all the cased characters[4]converted to lowercase. The lowercasing algorithm used is described in section 3.13 of the Unicode Standard 参考 https://docs.python.org/3/library/stdtypes.html#str.casefold https://segmentfault.com/q/1010000004586740/a-1020000004586838...

最近在学习Python基础和一些视频教学中,发现字符串的内置函数(built-in functions)中有2个方法的作用非常相似:casefold和lower: str1='I love Python'str1.casefold() str2=str1[:] str2.lower() 以上示例中,最后的输出结果都是'i love python'。
The str.casefold() function is used to convert strings in the Series/Index to be casefolded. The method is equivalent to str.casefold(). Syntax: Series.str.casefold(self) Returns:Series/Index of objects Example: Python-Pandas Code:
Python3 # Define a stringstring1 ="GeeksForGeeks"print(string1)# Store the output of lower() method# in string2string2 = string1.lower() print(string2) 输出: GeeksForGeeks geeksforgeeks Python 中的 casefold() 方法 在此示例中,我们在 string1 中存储了一个德文字母“ß”,并使用casefold(...
