compiling numpy, getting C source

[snippsat]

i read that some of numpy is written in C. i want to compile that code myself

There are a mix also use some FORTRAN code used,so need a FORTRAN 77 compiler installed.
There is documentation about this if you had search Building NumPy from source

Numba is also really good,eg just add parallel=True and it will use all your CPU cores or GPU cores.

Ship high performance Python applications without the headache of binary compilation and packaging.
Your source code remains pure Python while Numba handles the compilation at runtime.
We test Numba continuously in more than 200 different platform configurations.

Numba supports Intel and AMD x86, POWER8/9, and ARM CPUs, NVIDIA and AMD GPUs, Python 3.6-3.9, as well as Windows/macOS/Linux.
Precompiled Numba binaries for most systems are available as conda packages and pip-installable wheels.
