Where is class "list"?

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?

The "list" class that Kenneth is subclassing is the native Python standard list class.

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.
