I am using Google App Engine, but it seems that the problem is a
Python problem. I fixed the code a little bit, now I can print the
lists:

        Rep().replist = L
        Rep().put()
        query = Rep.all()
        for result in query:
            self.response.out.write(result.replist)

The output of this is:

[u'a', u'b'][u'a', u'b'][u'a', u'b']. . .

So, these are the lists in datastore. I want to take one of these
lists and apply list method on it. How do I do that? Thanks.
