This is NOT how uwsgi works!  You cannot use plain .py files with it,
and for good reason — CGI should be long dead.

What you need to do is, you must write a webapp — 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 = true
socket = 127.0.0.1:3031
chdir = /var/flask/
master = true
threads = 5
module = %n
callable = app
plugins = python
uid = http
gid = http
processes = 3


--- If /var/flask is a virtualenv, add:

binary-path = /var/flask/bin/uwsgi
virtualenv = /var/flask
