Well, I guess we should do that!

* Write some views. Open qandabear/views.py and put the following Python code in it:

<code>from django.http import HttpResponse

def index(request):

return HttpResponse("Hello, world. You're at the ~~poll~~ index.")</code>

return HttpResponse("Hello, world. You're at the questions index.")</code>

This is a very simple view.

* Save the views.py file, then go to [http://127.0.0.1:8000/~~polls~~/ http://127.0.0.1:8000/~~polls~~/] in your browser, and you should see that text.

* Save the views.py file, then go to [http://127.0.0.1:8000/questions/ http://127.0.0.1:8000/questions/] in your browser, and you should see that text.

<code>def question(request, question_id):

return HttpResponse("You're looking at question %s." % (question_id,))

def edit_answer(request, question_id, answer_id):

return HttpResponse("You're looking at the edit page for answer %s." % (answer_id,))</code>

* Add a little html to the ‘question’ view. Wrap the question_id in <strong> </strong> tags and verify that the view is indeed bold!

* Add and commit your code. Remember to write a good commit message that mentioned what changed (in English) and more details below.
