[英]Remove/Replace all whitespaces from a multi-lines string, except newline characters
I want to remove all whitespace characters from a multi-line string using regex. 我想使用正则表达式从多行字符串中删除所有空格字符。 What I am looking for is something like:
我正在寻找的是:
exp = re.compile("\s-[\r\n]")
exp.sub('', text)
Is there a regex that does the above. 是否有正则表达式执行上述操作。 Since the
text
is unicode, which has a possibility of other characters that could form the \\s
class besides [\\t\\v\\f \\r\\n]
, I cannot use [\\t\\v\\f ]
. 由于
text
是unicode,除了[\\t\\v\\f \\r\\n]
之外,其他字符可能形成\\s
类,我不能使用[\\t\\v\\f ]
。
Try this double-negative character class: 试试这个双阴性字符类:
[^\S\r\n]
