Regular expressions are way, WAY overkill for a simple find. Just use
the string methods. Instead of this:

import string
string.find("Norwegian Blue", "Blue")


just do this:

"Norwegian Blue".find("Blue")

For case insensitive find:

"Norwegian Blue".lower().find("Blue".lower())

(or better still, turn it into a function).
