Regex Ignore numbers in a string (python)

I have a text like this :

text = "hey , i am new here . number is 8,5%"

And i want my output to be like this :

hey, i am new here. number is 8,5%

So am using this regex code :

text= re.sub(r'\s*([.,?:])\s*', r'\1 ',text)

The output of this code is :

hey, i am new here. number is , 5%

I don't want the numbers to be touched with my regex code.

Am using Python3

You can use (?<!\d)\s*([.,?:])\s*.
(?<!\d) means "If not preceded by a digit"

Full piece of code: text= re.sub(r'\s*([.,?:])\s*', r'\1 ',text)

You can use

re.sub(r'\s*([?:]|(?<!\d)[.,](?!\d))\s*', r'\1 ',text)

See the Python demo and the regex demo.

Details:

  • \s* - zero or more whitespaces
  • ([?:]|(?<!\d)[.,](?!\d)) - Group 1:
    • [?:] - a ? or :
    • | - or
    • (?<!\d)[.,](?!\d) - a . or , not preceded nor followed with a digit
  • \s* - zero or more whitespaces.
