Find the index of the first digit in a string

Question

I have a string like

\"xdtwkeltjwlkejt7wthwk89lk\"

how can I get the index of the first digit in the string?

Answer 1

In Python 3.8+ you can use re.search to look for the first \d (for digit) character class like this:

import re

my_string = "xdtwkeltjwlkejt7wthwk89lk"

if first_digit := re.search(r"\d", my_string):
    print(first_digit.start())
