python中strip()和split()在无参数的情况下使用whitespace做为默认参数,在帮助文档中对whitespace的解释为6个字符,它们是space, tab, linefeed, return, formfeed, and vertical tab wiki的ASCII中对whitespace的定义多了一个backspace,它们是

空格和缩进(WhiteSpace and Indentation) 空格和缩进在Python语言中非常重要,它替代了其他语言中{}的作用,用来区分代码块和作用域。在这方面PEP8有以下的建议: 1、每次缩进使用4个空格 2、不要使用Tab,更不要Tab和空格混用 3、两个方法之间使用一个空行,两个Class之间使用两个空行 ...
) S.split([sep [,maxsplit]]) -> list of strings #sep为分隔符,默认为空格 最大分隔次数 Return a list of the words in the string S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace ...
Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns []. For example: >>> '1 2 3'.split() ['1', '2', '3'] >>> '1 2 3'.split(maxsplit=1) ['1', '2 3'] >>> ' 1 2 3 '.split() ['1', '2', '3']使用中...

This function finds all the substrings that match the given RegEx string, while the split() method uses the RegEx string as a delimiter. To use the findall() function to split the string using whitespace, negate the whitespace keyword \s by capitalizing the letter (\S). findall() ...
split 切割字符串,从左往右,默认切割全部,也可指定切割次数 rsplit 切割字符串,从右往左,默认切割全部,也可指定切割次数 splitlines 按行切割字符串 partition() 分割字符串,带有分割字符 join 字符串的拼接 isalnum 判断字符串是否完全由字母或数字组成
