Hummm... Isn't it easier and faster to solve this problem by hand than to code
a Python program for it? I had proofs for what has to be on both papers in
about 30 seconds... ;-)
If you're looking for things to code in Python, I'd rather suggest you look at
number theory than at logic problems. Basically, every logic problem can be
solved by exhaustive search (which is always the same algorithm), whereas a
number theory problem requires that you implement a certain algorithm from
scratch for each problem you're trying to tackle.
Implementing the sieve of Erathosthenes comes to mind straight away.
