Numpy array dimensions

Question

Numpy array dimensions

I'm as of now attempting to learn Numpy and Python. Given the following array:

import numpy as np

a = np.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.

import numpy as np   

>>> np.shape(a)

(2,2)

Also works if the input is not a numpy array but a list of lists



>>> a = [[1,2],[1,2]]

>>> np.shape(a)

(2,2)

Or a tuple of tuples



>>> a = ((1,2),(1,2))

>>> np.shape(a)

(2,2)

It is .shape:



ndarray.shape

Tuple of array dimensions.

Thus:



>>> a.shape

(2, 2)
