This is NOT how uwsgi works!  You cannot use plain .py files with it,
and for good reason =E2=80=94 CGI should be long dead.

What you need to do is, you must write a webapp =E2=80=94 in Flask, for
example.  Then you must craft an .ini file that mentions this.

With the http://flask.pocoo.org/ demo as /var/flask/hello.py
(copy-pasting from my working site):

--- nginx config --
location {
    include uwsgi_params;
    uwsgi_pass 127.0.0.1:3031;
}

--- /etc/uwsgi/apps-enabled/hello.ini ---

[uwsgi]
emperor =3D true
socket =3D 127.0.0.1:3031
chdir =3D /var/flask/
master =3D true
threads =3D 5
module =3D %n
callable =3D app
plugins =3D python
uid =3D http
gid =3D http
processes =3D 3


--- If /var/flask is a virtualenv, add:

binary-path =3D /var/flask/bin/uwsgi
virtualenv =3D /var/flask
