Playing with Python: deciding if two words are anagrams

Very little script I made that checks if two strings(or words) are anagrams:

def are_anagrams(string1, string2):
    string1 = list(string1.lower())
    string1.sort()
    string2 = list(string2.lower())
    string2.sort()
    return string1 == string2

If you thought: "Hey, dude, what's an anagram??", take a look here first. Also, this is a very nice online app that finds anagrams for words you provide: http://wordsmith.org/anagram/
