Just a note

I believe Aaron was just throwing out ideas since you requirements are
vague. In most cases C++ solution will be faster than pure Python. Sounds
like you want a disk based dictionary. I'd be curious how much C++ will buy
you in this case. Disk I/O will eat into your gains.

If you try this in Python avoid readline(), but there is a fast replacement
floating around.

My current paradigm is to code it in Python then push the slow stuff into
C++. The Python phase can really clarify the problem.

I'd like to hear how you solve this.
