I've a huge csv file and I want to read stuff from it again and again. Is it
useful to pickle it and keep and then unpickle it whenever I need to use that
data? Is it faster that accessing that file simply by opening it again and
again? Please explain, why?

Would be interesting to be able to pickle function.__code__.
