Since you use dictionaries, I guess that simple store saving key:value
If so, bsddb support built into Python will do just nicely.
bsddb is multiplatform, although I have not personally tested if a
binary db created on one platform will be usable on another. You'd have
to check this.
Caveat: from what some people say I gather that binary format between
bsddb versions tends to change.
There's also ultra-cool-and-modern Tokyo Cabinet key:value store with
I didn't test it, though.
