Where is the sys module located, or how to find it in Win 11 & Python

Question

Does anyone know how to find where the sys module is installed in a Windows 11 install of anaconda3 & Python? I've tried looking in the Lib folder already and although there is a file called sys.py, it seems awfully short for the number of methods exported by sys. I also tried sys.__file__ with no luck, does anybody know how I can find this thing?

Tried sys.__file__ but it did not return a path, I also tried searching in the Lib folder of anaconda3 with no luck.

It's not installed anywhere, it's baked into the interpreter itself. The module contains functionality that core Python relies on, and can't function without, so it's not a separately loaded module at all, even though you import it like one.

It's not even in the normal Modules directory of the CPython source tree (where C extension module source code normally lives; Lib is for modules implemented in Python), it's in the Python directory (where the core interpreter source code lives).
