NumPy - Array Manipulation

What is the output shape of the following code?

import numpy as np
arr = np.arange(12)
new_arr = arr.reshape(3, 4)
print(new_arr.shape)

A(3, 4)

B(4, 3)

C(12,)

D(2, 6)

Step-by-Step Solution

Solution:

Step 1: Understand the original array
np.arange(12) creates a 1D array with 12 elements from 0 to 11.
Step 2: Reshape to (3, 4)
The reshape changes the array to 3 rows and 4 columns, so the shape becomes (3, 4).
Final Answer:
(3, 4) -> Option A
Quick Check:
reshape(3,4) = (3,4) shape [OK]

Quick Trick: reshape dims become shape tuple [OK]
