Write a function to make ordinals, e.g. this one taken from this excellent answer:

def make_ordinal(match):
    n = match.group(0)
    n = int(n)
    suffix = ['th', 'st', 'nd', 'rd', 'th'][min(n % 10, 4)]
    if 11 <= (n % 100) <= 13:
        suffix = 'th'
    return str(n) + suffix

and use regular expressions to do the replacement, using re.sub:

import re

s = "I was born in September 22 and I am 1 in swimming"

re.sub(r"\d+", make_ordinal, s)
# 'I was born in September 22nd and I am 1st in swimming'
