OK for real. :-)
I've always liked Python for web dev because it is a good general purpose language, it's elegant, and has good web frameworks. Some other languages are really good at the web but not much useful outside of that. So with Python if you are building something with data analytics and the web it's a perfect choice. Python pairs well with a lot of areas. It doesn't pair with everything well, such as, Javascript I think pairs better with robotics. And there are other good general purpose languages too (Javascript, Java, etc).
