Replace With Alphabet Position

Welcome.

In this kata you are required to, given a string, replace every letter with its position in the alphabet.

If anything in the text isn't a letter, ignore it and don't return it.

"a" = 1, "b" = 2, etc.

Example

alphabetPosition("The sunset sets at twelve o' clock.")

alphabet_position("The sunset sets at twelve o' clock.")

alphabet_position("The sunset sets at twelve o' clock.")

Kata.AlphabetPosition("The sunset sets at twelve o' clock.")

alphabet_position('The sunset sets at twelve o\' clock.');

alphabet_position("The sunset sets at twelve o' clock.");

text:  db  "The sunset sets at twelve o' clock.",0h0

main:
    mov rdi, text
    call alphabet_position

alphabet_position("The sunset sets at twelve o' clock.")

alphabetPosition("The sunset sets at twelve o' clock.")

Kata.alphabetPosition("The sunset sets at twelve o' clock.")

Should return "20 8 5 19 21 14 19 5 20 19 5 20 19 1 20 20 23 5 12 22 5 15 3 12 15 3 11" (as a string)

Solution

import re
def alphabet_position(text):
    return ' '.join(str(ord(c) - 96) for c in re.sub('[^a-zA-Z]', '', text.lower()))
