Join HTML Frontend with Python Backend

Good evening. I'm kinda new in python when it comes to web development. I have a HTML frontend made of 5 html files, a css stylesheet and javascript, it's validated according the W3C Standards. In the backend, I have a python 2.7 file, everything in a debian server. It's stable and it works. Everything is going pretty well, except that I have to parse values from html text inputs to python. I'm really a novice at this and I can't join the html to the python script. Is there any way to do this without using web frameworks? The deadline is very soon and I only need to join the html with python. Sorry for my bad english and thanks for your attention.
