How to avoid computation every time a python module is reloaded

Question

I have a python module that makes use of a huge dictionary global variable, currently I put the computation code in the top section, every first time import or reload of the mod

I'm going through this same issue... shelve, databases, etc... are all too slow for this type of problem. You'll need to take the hit once, insert it into an inmemory key/val store like Redis. It will just live there in memory (warning it could use up a good amount of memory so you may want a dedicated box). You'll never have to reload it and you'll just get looking in memory for keys

r = Redis()
r.set(key, word)

word = r.get(key)
