Wondering when a function is treated as a "builtin". Are numpy, opencv, scipy, pandas, etc which are wrappers for compilied implementations "builtins"?

There is a note to run a manual test using scipy/numpy, but I cannot find a tests script or further details:
https://github.com/sumerc/yappi/blob/master/tests/manual_tests.txt

This test uses "yappi.start(builtins=True)" when using testing "old style co-routines" with asyncio, but not for all asyncio tests:

A builtin function means any function that is implemented in C API. Any standard library function that is implemented on a C extension (for example: time.sleep is implemented in a C module) or any 3rd party C extension function.

So, coming to your original question: I assume there are lots of builtin functions in these libraries(numpy, scipy, pandas) as there are lots of code implemented in C.

Just for reference, for more information on what functions are builtins, this is where it is defined in CPython: (PYCfunctionObject struct) https://github.com/python/cpython/blob/0ab152c6b5d95caa2dc1a30fa96e10258b5f188e/Objects/methodobject.c#L44
