Python Disk-Based Dictionary

Question

I was running some dynamic programming code (trying to brute-force disprove the Collatz conjecture =P) and I was using a dict to store the lengths of the chains I had alread

Answer 1

I've read you think shelve is too slow and you tried to hack your own dict using sqlite.

Another did this too :

It seems pretty efficient (and sebsauvage is a pretty good coder). Maybe you could give it a try ?
