Rearranging letters

[Cubedude04]

Hey

This is my first post here and i hope you can help :)
I would like to create a very basic easy program that can rearrange letters.
It would take the inputed word process it and print the new word out

for example if you entered the word job it would move each letter 3 spaces backwards so the printed result would be "gly"

What would be the best way to approach this

Thankyou in advance

Make a string of ascii letters:

>>> import string
>>> string.ascii_lowercase
'abcdefghijklmnopqrstuvwxyz'
>>> letters = string.ascii_lowercase

The string index of each letter can be found by using the string method index(). Subtract 3 from the index number, and get the new letter from the string using the slice operator.

>>> word = 'job'
>>> ''.join([letters[letters.index(letter)-3] for letter in word])
'gly'
>>>

>>> s="def"
>>> ''.join([chr(ord(ch)-3) for ch in s])
'abc'

That worked great thanks alot :)

I wrote it line by line into the python command line. Is there anyway to copy it out like into a text file and just change the word whenever i want menaing i don't have to repeatly write it out for just one word

thanks in advance

Edit: That was to the first reply. I will look at the second reply now

edit again: They both worked great. Now if i can only work out how to save it i will be sitting good :D
