What does this code output?

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

A(4,)

BError: no attribute 'shape'

C[2, 2]

D(2, 2)

Step-by-Step Solution

Solution:

Step 1: Understand shape attribute
arr.shape returns a tuple with the dimensions of the array.
Step 2: Identify array dimensions
arr is 2 rows by 2 columns, so shape is (2, 2).
Final Answer:
(2, 2) -> Option D
Quick Check:
Array shape attribute = B [OK]

Quick Trick: Use .shape to get array dimensions as tuple [OK]
