Change numeric base using Python

Hello,

How to change the numeric base of a number? This is a implementation in Python.

def convert(decimal,newBase,str,letters):

        if decimal >= newBase:

                x = decimal % newBase

                y = decimal / newBase   

                str = letters[x] + str

                if y < newBase:

                        str = letters[y] + str

                return convert(y,newBase,str,letters)   

        else:

                if len(str) == 0:

                        str = letters[decimal] + str

                return str

let = "0123456789ABCDEF"

print convert(17,16,"",let)

The variable let means what values used in the base. For an example if you want binary you should replace with 01.
