[Solved] Find the error in this code:import numpy as np arr = np.array([1, 2, 3]) result = arr * 2 print(result[3]) | NumPy

NumPy - Array Operations

Find the error in this code:

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

ATypeError: cannot multiply array by int

BSyntaxError: invalid syntax

CIndexError: index 3 is out of bounds

DNo error, prints 6

Step-by-Step Solution

Solution:

Step 1: Check array size after multiplication
Multiplying by 2 keeps array length 3: [2, 4, 6].
Step 2: Accessing index 3 causes error
Index 3 is out of range (valid indices: 0,1,2), causing IndexError.
Final Answer:
IndexError: index 3 is out of bounds -> Option C
Quick Check:
Accessing invalid index = IndexError [OK]

Quick Trick: Array indices start at 0; max index is length-1 [OK]
