How to get character position in alphabet in Python 3.4?

I need to know the alphabet position of the n-th character in a text and I read the answer of this question but it does not work with Python 3.4.

My program:

# -*- coding: utf-8 -*-

import string

message = 'bonjour'
string.lowercase.index('message[2]')

It does not work with ascii_lowercase instead of lowercase too.

The error message:

runfile('C:/Users/Asus/Desktop/Perso/WinPython-64bit-3.4.3.4/python-3.4.3.amd64/Scripts/ESSAI.py',
wdir='C:/Users/Asus/Desktop/Perso/WinPython-64bit-3.4.3.4/python-3.4.3.amd64/Scripts')

Solution

import string
message='bonjour'

print(string.ascii_lowercase.index(message[2]))

o/p

This will work for you, Remove the ' in change index.

When you give '' then it will be considered as a string.
