Error on first example

[quarinteen]

Hello I just purchased your book, and I am on the first example "scrapetest.py", and I am getting an error.

Exception has occurred: NameError
name 'null' is not defined
File "C:\Users\mine\Documents\VSCode\Workspaces\PythonScrapping\scrapetest.py", line 114, in "execution_count": null,

It is a fresh install o vs code, and python 3.1. This is my first time running them. Any help is appreciated.
