The downvotes are hilarious. Being able to drop down to C is one of python’s selling points, and the title of the post includes the name of the python ref implementation __C__Python.
There is a difference being able to drop down in C and using exclusively C.
One of the main advantage of python is being to quickly write code, and using C-based library / part of code written in C (or fortran, or rust for what it matters) when needed.
