A few hints: - You shoulld just split the line once and save the result - the current code splits the line several times for each word. - You could make a generator that returns pairs of words, that would simplify the loop code. - There is a difference between making the code fast for a single test, and making it fast for many tests. For a single test, the best solution is probably something like what you have, computing the numbers you need as you make a single pass through the data. For multiple tests, you will do better if you create some helper dictionaries that allow you to look up words and pairs quickly. You could use the pickle module to save the dicts and re-read them on subsequent runs. HTH - I can't flesh these out right now.
