Beginner Problems - Web Development with Python 2

Hello, this is my first attempt at creating a website, and my first real experience with Python.

I am receiving an error that is not present in the "Web Development with Python 2" video. It appears as though "webapp" and a few other functions are undefined (there is a squiggly line underneath the word). Even keywords like "backends.sqlite" - contained in the settings.py container appear undefined.

Included within my problem is the return I receive after trying to "runserver" following the creation of the webapp (included below).

I have to add that I have rewatched the first two videos three times and triple checked all of my spelling to match what you have written in your videos. Can you think of a reason why I am unable to successfully launch the website?
