<s>[INST] Numpy array dimensions I'm currently trying to learn Numpy and Python. Given the following array:
import numpy as N
a = N.array([[1,2],[1,2]])

Is there a function that returns the dimensions of a (e.g.a is a 2 by 2 array)?
size() returns 4 and that doesn't help very much. 
 [/INST] It is .shape:

ndarray.shape
  Tuple of array dimensions.

Thus:
>>> a.shape
(2, 2)
