Connecting existing web interface with python backend [implementing a mini youtube]

I implemented a mini youtube page but I need better algorithms for video suggestions. Currently, suggested videos are listed randomly. I'm trying to implement the backend(mostly algorithms) in python. I was going to do everything in javascript but each video file is also associated with text data. The mini youtube page has videos listed along with some text info. User has the option to click the text and the server side will take that "click" into consideration for suggestion. I have 80 videos now and there's a hard coded array with all the video paths in. What framework should I use? I was trying to use Django. Is that a good idea for this project? If so, how exactly can I link existing interface with python backend?
