I know these posts where the coder brags about how much they sped up their code are pretty boring but this is one case where I just can't resist. I have a code of about 6000 lines, I spent 36 minutes planning how to write the code, and then 33 minutes actually writing 19 lines of new code. Without one bug, I managed to speed the code up from .045 seconds per input to .035 seconds per input! Basically what I did is I have a program that finds contradictions in sentences. I noticed that there was one set of sentences that were irrelevant so I just figured out a way to not search through the irrelevant sentences.

That is definitely one of the most successful coding periods I've ever experienced. This really helps to ease the pain I felt the other day when I spent 4 hours looking for a bug which was caused by downloading the natural language toolkit and forgetting that I installed python 3.4 which messed up my code because my code relies on ordered dictionaries which they have in python 3.6.
