Dimension in python numpy

Question

I am new to python and its various libraries. Currently, I am learning numpy and want to know if there is any function which will return the dimension of my array. For example:

Import numpy as np
arr=np.array([[1,2],[3,]])

I want to know its dimensions whether it’s a 2-d array or not. I even use the shape function but that could not come to my use.

Answer 1

Use the .shape to print the dimensions of the array.

import numpy as np
arr=np.array([[1,2],[3,4]])
arr.shape

Output – (2,2)
