RestFul in python, which framework to choose?

Question

Python

Good afternoon. It was required to make rest api on a python.
I can't decide on a framework. Django rest framework? Or is a tornado better suited for these purposes?
For the most part, requests from clients will be lightweight. The hardest part is uploading photos to the server.
It is also necessary to organize a server for a chat between two people (mobile application clients)
for a chat I tend to tornado more.
Seek advice from knowledgeable gurus

Answer 1

Flask + Flask-RESTFul

Chat - tornado
