As a programmer, I know that grep, sed and awk are powerful for processing text, but they sometimes aren't that straight-forward for specific tasks, as I need to think about how to filter the lines and the columns out. So I wonder if there is a handy way to do these tasks? After using it for a while, I think using regex directly can help, so I launched a re.findall service building on top of Python re.findall API.
