我需要替换文本中所有不正确出现的昏迷

jlkj,jlkj
jlkj, jlkj
jlkj,jlkj
jlkj , jlkj

对于,，这意味着对于所有情况，结果都是jlkj, jlkj。
我想出的模式不起作用：(.*),(.*)

用途

re.sub(r'\s*,\s*', ', ', your_string)

参见regex proof。

REEX101解释

\s* -  matches any whitespace character (equivalent to [\r\n\t\f\v  ])
       between zero and unlimited times, as many times as possible, giving 
       back as needed (greedy)
,   -  matches the character , with index 4410 (2C16 or 548) literally
\s* -  matches any whitespace character (equivalent to [\r\n\t\f\v  ])
       between zero and unlimited times, as many times as possible, giving 
       back as needed (greedy)
