You may use a simple regex with capturing group:

import re
s= "3 roof 4 bath"
search_word = "bath"
res = re.search(r'(\d+)\s*{0}'.format(re.escape(search_word)), s)
if res:

See the Python demo


  • (\d+) - Group 1: one or more digits are captured into Group 1 (note: if the number can contain commas or periods, use [\d,.]+ instead of \d+, or a more precise \d+(?:[,.]\d+)*)
  • \s* - 0+ whitespaces
  • {0}' - a placeholder for the search word whose chars are escaped withre.escape()` in order to match even if there are special regex chars in it

To access the digits, use .group(1) on the match data object.
