Why am I getting this syntax error in my python-jinja2 app

Question

I am new to python and the google app engine. I am trying to create this app that fetches feed from yahoo pipes and displays it using jinja2 templates. However I am getting a syntax error and I am not understanding the reason behind it.

import webapp2 from webapp2_extras import jinja2 import logging

import feedparser  
import urllib

class BaseHandler(webapp2.RequestHandler):
    @webapp2.cached_property
    def jinja2(self):
        return jinja2.get_jinja2(app=self.app)

    def render_response(self, _template, **context):
        rv = self.jinja2.render_template(_template, **context)
        self.response.write(rv)

class MainHandler(BaseHandler):
    def get(self):
        feed = feedparser.parse("http://pipes.yahoo.com/pipes/pipe.run?_id=1nWYbWm82xGjQylL00qv4w&_render=rss&textinput1=dogs" )

        feed = [{"link": item.link, "title":item.title, "description" : item.description} for item in feed["items"]
        context = {"feed" : feed, "search" : "dogs"}
        self.render_response('index.html', **context)

        def post(self):

            terms = self.request.get('search_term')

            terms = urllib.quote(terms)
            feed = feedparser.parse("http://pipes.yahoo.com/pipes/pipe.run?_id=1nWYbWm82xGjQylL00qv4w&_render=rss&textinput1=" + terms )

            feed = [{"link": item.link, "title":item.title, "description" : item.description} for item in feed["items"]]

            context = {"feed": feed, "search": terms}

            self.render_response('index.html', **context)

app = webapp2.WSGIApplication([
    ('/', MainHandler)
], debug=True)

Here is the index.html file

<!DOCTYPE html>
<html>
<head>
<title>Byte 1 Tutoral</title>
</head>
<body>
<h1>Data Pipeline Project Byte 1 Example</h1>
<form action="search" method="POST">
  Search Term: <input name="search_term" value={{search}}><br>
  <input type="submit" value="Enter Search Term">
</form>
{% if search: %}
<p>Searching for {{search}}</p>
{% endif %}


<h2>Feed Contents</h2>
{% for item in feed %}
<a href="{{ item.link }}">{{ item.title }}</a><br>
{{item.description|safe}}
<br>
{% endfor %}


</body>
</html>

and this is the error that I am getting.

Traceback (most recent call last):

  File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 239, in Handle

    handler = _config_handle.add_wsgi_middleware(self._LoadHandler())

    handler, path, err = LoadObject(self._handler)

    obj = __import__(path[0])

  File "C:\googleapps\ykelkar-byte1\main.py", line 38

    context = {"feed" : feed, "search" : "dogs"}

There should be one more ] at then end of line37:

feed = [{"link": item.link, "title":item.title, "description" : item.description} for item in feed["items"]]
