Ok so like you have two popular alternatives: django and flask. But before you dive deep into python libraries convince yourelf that a large portion of front end talking to backend is a module known as an 'RESTful Application Programming Interface' or API. I promise all of this is way easier than it sounds. An rest api is just a module of code (flask,django,nodejs) that runs perpetually waiting for HTTP get and post requests. Just go through any basic youtube tutorial, there are thousands: and whenever you get stuck search for solutions on stackoverflow, if your problem has not been asked yet post a question yourself; most answers are given within like 6 hours. Sorry I know you know how stackoverflow works :'p Just don't be reluctant to post questions because you are bound to run into problems, a very popular one for example is that when returning a json object as a http response most learners do not add the "Access-Control-Allow-Origin" header which then blocks the client server communication across platforms in python-flask: res.headers.add('Access-Control-Allow-Origin':'*'); Also, an additional recommendation, before you upload your python code to heroku 1.make a 'requirements.txt' file in the directory you want to upload 2.open terminal and run the command 'pip freeze'. You'll get a list of all the libraries you have installed. Copy this list as it is and paste it in requirements.txt (if you're using Linux run the command 'pip freeze>requirements.txt') 3.install gunicorn by running command 'pip install gunicorn' 4.make another textfile name it procfile and put this code fragment in it 'web:gunicon :app' so if your code is in server.py 'web:gunicorn server:app' This is all info you will come across in your learning process anyways just giving a heads up.
