Hi, I'm new here. I have been Python coding for 6 weeks pretty seriously on a daily basis and writing avant-garde poetry for years. I made a script today for using a Markov chain to generate a poem line by line, including a corpus text of about 2,600 sentences that I have on my GitHub. This isn't necessarily for production, but it is usable. It's excellent to generate ideas for phrases and lines.

This is the first thing I've developed that has some level of real value to me. None of it was written by AI. The script is here for your viewing pleasure. You can find the .py file and poetry lines CSV for the corpus at my GitHub if you want to try it out in an IDE:
