how to get the memory address of a numpy array for C

Question

I constructed an numpy array::

a=np.ndarray([2,3]) 

then i want to see where its data are::

a.data 
>>>Out[213]: &         


        

Answer 1

a.data might be a property whose getter function creates a new buffer object (meta data) on each call.

To get the address see how numpy.ctypeslib.as_ctypes() is implemented.
