Kenneth created a new file call hands.py. Inside this file, there is class Hand(list). My question is, where is the class "list" which Hand is extending? I don't think any class was created with the name list. So why was he extending a class that was never declared anywhere?

You are already familiar with square bracked notation for instantiating an empty list.
x = []
and this is equivalent to instatiating with the Python standard list class.
x = list()
The actual source code is implemented in 'C' language and is compiled to native binary for your particular platform. In case you are curious about this code. I linked the repository below.
