Sudoku Solver

This is a naive attempt at a Sudoku Solver in Python. It takes input as 9 lines of digits 0-9 then iterates over all cells, trying to find potential values for a given cell. When it establishes that a cell can only have one possible value, it sets that value to that cell and carries on.

I've done no research on efficient algorithms for doing this, and wrote this in about 2 hours one evening, mainly to play with a bit of Python (which I haven't touched in some time), and because I've always wanted to write a Sudoku solver.

Now also available as a service.

Usage

Note: Written for and tested on Python 2.7.
