#Problem

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 being 1, b being 2, etc. As an example:
alphabet_position("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


def alphabet_position(text): 
    output = ''
    for c in text.lower(): 
        if c.isalpha():
            output = output + str(ord(c) - 96) + ' '
    output = output.strip() #strip the bare space
    return output
