How do I keep track of my solved problems?

I previously used to solve projecteuler and it has a very nice feature where it keeps a track of your solved problem. Therefore, if I login next time I don't have to solve the problems again.

How to achieve the above functionality with pythonchallenge because every time I open the website I am presented with level-0 problem even when I had already solved it.

The way I do this is via a private git repository

The template I use for my files is:

  Code:

#!/usr/bin/env python
