I had need for a parser written in Python, so I investigated the available Python parser generators. I found more than I thought I would (sixteen!), and my head was swimming with all the choices and differences. So I started taking organized notes. It seemed like something others would find useful, so I present it to you: Python Parsing Tools.
It’s incomplete and disorganized, but I would like to keep it up to date and/or improve it. Let me know if you have changes to the information there.
