Checking out the Wikipedia API
You're doing so well and having so much fun that we're going to throw one more API at you: the Wikipedia API (documented here). You'll figure out how to find and extract information from the Wikipedia page for Pizza. What gets a bit wild here is that your query will return nested JSONs, that is, JSONs with JSONs, but Python can handle that because it will translate them into dictionaries within dictionaries.
The URL that requests the relevant query from the Wikipedia API is
https://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&exintro=&titles=pizza
This exercise is part of the course

pizza_extractholds the HTML of an extract from Wikipedia's Pizza page as a string; use the functionprint()to print this string to the shell.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Import package
import requests
