Setting up a Python server with Angularjs app and capture user input

Is it possible to help me please, just a hint or a useful tip if you know something better than this approach.

I've developed a list of forms with HTML and AngularJS, that for each form when the users submits, the input data is collected into a stack of json-string data.

I'm looking for a way to:

• post this data in a python server
• process it with python code
• render the result on the page (view)

I set up a Flask server and it does just print the html without binding with AngularJs. When I tried to set it up with SimpleHttp python command it worked (but I don't know if it is possible to manipulate the data ?)

Thanks for your attention, and sorry if it not concise.
