regular expression to extract "5 rnd" from "5 Rnd (5-5-5-5-5)"

Question

To put it simply, from "5 Rnd (5-5-5-5-5)", I need to extract the "5 Rnd" part, where the number could be any number, and the "Rnd" is sometimes written "rnd", sometimes "RND", or sometimes just "Rnd"

Answer 1

Try:

txt - input text

import re
re.findall("\d+\s*rnd", txt, re.I)

\d+ 1, or more digits

\s* 0 or more spaces

rnd letters "rnd"

re.I case insensitive search
