I just cannot thank you enough - you are a life saver. Coming from Java world I was looking for exactly like this. Maybe I'm new to Python, I was just about to give up. Setting Nginx/Apache for Flask was giving me nightmares -just could not get it right to play with gunicorn, uwsgi and so on.
I know Java is verbose but the tooling is good. Just put you war(a pre-defined structure) in Tomcat webapps dir and your good to go with a fairly scalable web site. I was so surprised it wasn’t that easy for Python. I think it stems out that Python is more of systemish kinda ecosystem.
