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

The 3rd party shove module is also worth taking a look at. It's very similar to shelve in that it is a simple dict-like object, however it can store to various backends (such as file, SVN, and S3), provides optional compression, and is even threadsafe. It's a very handy module

from shove import Shove

mem_store = Shove()
file_store = Shove('file://mystore')

file_store['key'] = value
