This is a Twitter chatbot that respond to every tweet he's tagged in by running the text in python.
This bot is live right now, although it's still in the testing stage, here's a link: https://twitter.com/CodeBot5 Please feel free to test him :)
If you tag him in a tweet saying: 4*sum((-1.0)**(n%2) / (2*n + 1) for n in range(2010)) he'll reply with: 3.1410951411827663
Here is the example working: https://twitter.com/CodeBot5/status/1041475137105784833
