This seems to be literally looking at the details of the C implementation of a Python interpreter. Exactly specifying the implementation makes sense here. You wouldn't say "how does the C++ compiler work" then look only at gcc.

c++ / g++ is not comparable because the original c++ reference compilers are not commercially popular today. No one is using Strouvestroups compilers.

CPython is Python. Every time your buddy says “just download python” you are using CPython . There’s no reason to be pedantic.

If you know enough about Python to look at how the dict is implemented, you also know the difference between Python and CPython. It's not a beginners intro.

g++ and clang are comparable. You need to specify the implementation.
