Surprising no-one else mentioned a fairly typical pattern for this sort of situation - the compromise between "read from disk" and "read from memory" is "implement a cache". I've had lots of good experiences hand rolling simple caches, especially if there is an application specific access pattern. Python has nice implementations of things like tuple and dictionary which make caching fairly easy compared to other languages. -- https://mail.python.org/mailman/listinfo/python-list
