Problems with the Tutorial part 3

I am getting an error when I go to http://localhost:8000/polls/after adding working on the changes in part 3. The message is:

Reverse for ‘index’ with arguments ‘(’’,)’ not found. 1 pattern(s) tried: [‘polls/$’]

I think I messed up editing the changes required for the tutorial.
Is there a completely worked set of tutorial files?


Working through the process and learning to recognize errors and mistakes are part of the learning process. The project isn’t as important as what you learn along the way.

So with that in mind, if you post your file(s), we’ll look at them and help you find where the mistake may be.
