Check for a cookie with Python Flask

I would like to get a cookie (e.g. country) with this Flask call.

data = request.cookies.get("country")

How can I tell if the cookie exists?

request.cookies is a dict, so:

from flask import request

if 'country' in request.cookies:
    # do something
else:
    # do something else

request.cookies.get('my_cookie')

should have worked. If it didn't work, you may not have access to the request object when you call this line.

Try importing flask at the top 

import flask

then call

cookie = flask.request.cookies.get('my_cookie')

If the cookies exists, it will get assigned to cookie and if not then cookie will equal None
