Is there any way to get the repeating decimal section of a fraction in Python?

decimal, precision, python

Solution

Since giving the answer could be a spoiler for project euler (which is generally not done here at stackoverflow), I'd like to give this hint: read this (section 1.2 should ring a bell).

Problem

I'm working with fractions using Python's decimal module and I'd like to get just the repeating part of a certain fraction. For example: if I had 1/3 I'd like to get 3, if I had 1/7 I'd like to get 142857. Is there any standard function to do this?
