Convert a python module to work on a web

I have written a python module that performs classification via neural networks: once trained, it takes an example (an array of numerical values) and returns a class (A, B.)

Now, I would like to use it to classify users on a website, according to their behavior. It seems a quite standard task, but I have no idea on how to do it practically. Should I convert this module in another language? Create an api? Where should I put it in throe website?

I have zero knowledge about web programming and how it works, so any help (or tutorial) is more than appreciated.
