regex for repeating characters in a string in Python -


I'm new to reggax. I have a regex that removes repeating characters from the string.

  & gt; & Gt; & Gt; Self.repeat_regexp = re.compile (r '(w) * (\ w) \ 2 (\ w *)') & gt; & Gt; & Gt; Self.repl = r '\ 1 \ 2 \ 3'   

Two lines of code combine repeating characters. For example, loooooooove goes to love .

But I want to change the regex pattern, as if it only changes when repeating characters again 3 times. Expected Output:

  can not> --- Loooooooove can not ---- & gt; Love   

does not understand me as regex r '(\ w *) (\ w) \ 2 (\ w *)' ' and r \ 1 \ 2 \ 3 ' The above regexs can be understood if it makes sense.

let me regex -> R '(\ w *) (\ w) \ 2 (\ w *)' and 'r' \ 1 \ 2 \ 3 'the meaning of the above regex can be understood. differs depending on the digits, underscore, location setting, Face to French characters with frames), zero or multiple times (using quantifiers * ).

Next it is just a word character (\ w) â ???? And then using the same character again, using \ w , which is back to the context for the second match in the expression, which is the \ W

And after that, then zero or multiple word characters are the same as the beginning.

If that expression matches, then self.repl = r '\ 1 \ 2 \ 3' it changes "again, use references back ??? ?

With matching that capturing subpoters on brackets in the search pattern

Repeated character match except \ 2 , which does not contain grouping brackets.

Therefore, if you want to repeat four At least three times, you modify that part (\ w) (\ 2 {2,}) of expression ' â ???? {2,} is another quantifier which only says one- If only the preceding pattern happens at least twice (only at least twice , since the first letter already matches (\ w) .) < / P>

I did not find it working using the main and the following (\ w *) though ??? But since these also match zero word characters, I think That they are completely deceived

So you should do what you want to achieve:

  self.repeat_regexp = re compile ('r' (\ w) (\ 1) 2,}) 'self.repl = r' '1'   

(Since I removed the main capturing subpage here, <2 to \ 1 , is now referring to the first capturing subpot.)
