How do I read numpy source?

python class numpy dir

np.array is not a class itself, just a convenience function to create an np.ndarray
ndarray is just aliased to multiarray, which is implemented in C code (I think in an .so i.e. shared object, compiled code)
You can start looking at the ndarray interfaces here in numeric.py.
Most of the meat of the implementation is in C code, here in multiarray.
array() is implemented in core/src/multiarray/methods.c in array_getarray()
