Investigate how Python programs integrate with builtin types written in C

[wunused]

For example, in the following program:

class MyTuple(tuple):
    pass

MyTuple inherits from the builtin tuple, which is implemented in C.

What connects the tuple builtin with its C implementation? Where are the methods of a tuple object defined, so that we can figure out what the inherited methods of MyTuple are?

[HassamGani]

Methods of builtins can be found via dict, which outputs the namespace. From there, we save what's defined in the namespace as one of the following C methods types: FunctionType,
BuiltinFunctionType,
WrapperDescriptorType,
MethodDescriptorType,
MemberDescriptorType,
GetSetDescriptorType.

Note: these aren't written directly in C but instead presented under the hood
