How do I read numpy source?

Question

I built it myself on Python 3.3, but I can't for the life of me find the class definition of numpy.array(). I've looked all through the code and even found the core C files, but where is the dang array class??

Can anyone tell me what directory to look in, or how to find out from the python shell?

Answer 1

• np.array is not a class itself, it's just a convenience function to create an np.ndarray.
• ndarray is aliased to multiarray, which is implemented in C code (an extension module in .so/.pyd file, 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().
