HTML output problems

I am writing a website with python and jinja2 in google app engine. My html page is showing this on the page:

Status: 200
Content-Type: text/html;
charset=utf-8
Cache-Control: no-cache
Content-Length: 432

Any idea where this problem is coming from? Also, why is {{ initial_city }} not displaying the results?

My main.py script is:

from google.appengine.ext import db
from google.appengine.api import memcache
from models import Deal
import os
import webapp2
import jinja2


#databasestuff
deal = Deal(title='Hello',
        description='Deal info here',
        city='New York')
deal.put()
print deal


jinja_environment = jinja2.Environment(autoescape=True,
    loader=jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__), 'templates')))

class MainPage(webapp2.RequestHandler):
def get(self):
    template = jinja_environment.get_template('index.html')
    self.response.out.write(template.render())


class DealHandler(webapp2.RequestHandler):
def get(self):
    def get_deals(choose_city, update=False):
        key = str(choose_city)
        all_deals = memcache.get(key)
        return all_deals

    choose_city = self.request.get('c')
    try:
        initial_city = str(choose_city)
        choose_city = initial_city
    except ValueError:
        initial_city = 0
        choose_city = initial_city


    template = jinja_environment.get_template('deal.html')
    self.response.out.write(template.render())




class ContentHandler(webapp2.RequestHandler):
def get(self):
    template = jinja_environment.get_template('content.html')
    self.response.out.write(template.render())

app = webapp2.WSGIApplication([('/', MainPage),
                           ('/deal', DealHandler),
                           ('/content', ContentHandler)],
                          debug=True)

My html page:

<!DOCTYPE html>
<html>
  <head>
    <title>
      Deallzz: Chosen City: {{ initial_city }}
    </title>
  </head>
  ...

To display initial_city, pass the variable to the template using the render method:

self.response.out.write(template.render(initial_city = initial_city))

Its the "print deal" that is causing the problem. Its being output before any response.write

This is just the headers of the HTML page. You should provide more informations/code of what you are trying now.
