In Python, functions are first class citizens (a function is an object
you can bind to a variable, pass as an argument, return from another
function etc...), so methods *are* actually attributes...

BTW, in 1.5.x, you can use the String module instead of string class

import String
s = "allo"
String.index(s, "a")

but really, consider upgrading to a newer version...
