Reuse part of a Regex pattern

Question

Consider this (very simplified) example string:

1aw2,5cx7

As you can see, it is two digit/letter/letter/digit values separated

Answer 1

import re
digit_letter_letter_digit = re.compile("\d\w\w\d") # we compile pattern so that we can reuse it later
all_finds = re.findall(digit_letter_letter_digit, "1aw2,5cx7") # finditer instead of findall
for value in all_finds:
    print(re.match(digit_letter_letter_digit, value))
