You can do this! Remember the args is a dictionary, you can access information with a key like so:

args['password']

What you need to do is determine IF the password and confirm_password are the same, if they are, you can create a user, if not you just need to

raise Exception

Hope this helps! If you have any other questions fire them over

There were two extra lines with

self.reqparse = reqparse.RequestParser()

Removing the second two instances of it resolves the issue you are having.
