import numpy as np
a = np.arange(10)
id(a)

Here we know that id function return the identity of the object 'a'. Suppose that we only know the id of object(139806990767008 int or long), How can I get the data from 139806990767008 returned by id function. Or get which object's id is the 139806990767008.

Out of curiosity, why would you need to do this? – Blender Mar 18 '17 at 03:37
id's can be reused after objects are deleted, so if your objects come and go, then looking them up by id can easily get you a different object than you wanted. – PaulMcG Mar 18 '17 at 03:43
i need to read data from the file in different times, so i want to pass the i/o, use the data directly. – Li Ziming Mar 18 '17 at 03:54
Do *not rely on this solution*. – juanpa.arrivillaga Mar 18 '17 at 03:57
@LiZiming how does this solve that problem? This isn't the memory address of the data *on disk*. – juanpa.arrivillaga Mar 18 '17 at 03:57
