Was going to use python to process dozens of csv files each containing over 40 thousand rows. Had to download a couple of libraries to do some basic column modifications. Instead I gave AWK a try. It was as straightforward as you like. With just a couple of lines I processed all of these files with great performance and no extra dependencies.
