NumPy - Broadcasting

Consider the code:

import numpy as np
x = np.ones((2,3))
y = np.ones((3,2))
z = x + y

What error will occur and why?

AValueError because shapes (2,3) and (3,2) are incompatible for broadcasting

BTypeError because arrays have different data types

CNo error, result shape is (2,3)

DSyntaxError due to invalid addition

Step-by-Step Solution

Solution:

Step 1: Check shapes of x and y
x shape is (2,3), y shape is (3,2). Compare dims right to left: 3 vs 2 and 2 vs 3.
Step 2: Apply broadcasting rules
Neither dimension matches or is 1, so broadcasting fails and raises ValueError.
Final Answer:
ValueError because shapes (2,3) and (3,2) are incompatible for broadcasting -> Option A
Quick Check:
Broadcasting fails if dims differ and neither is 1 [OK]

Quick Trick: Broadcast dims must be equal or 1; else error [OK]

Common Mistakes:

Assuming addition works despite shape mismatch
Confusing error type as TypeError or SyntaxError
Ignoring dimension order in shapes
