    You cannot use regular expressions to do mathematical operations. You could use it to extract the number from the text to a variable, add +1, then replace the number with regex Commented Mar 27, 2022 at 21:56

    Just use a re.sub with a callable as replacement argument. re.sub(r'\d+', lambda x: str(int(x.group())+1), s). See ideone.com/dX1C96 Commented Mar 27, 2022 at 21:57
