NumPy - Array Manipulation

Find the error in this code snippet:

import numpy as np
arr = np.array([[1, 2], [3, 4]])
flat = arr.flatten
print(flat[0])

Aflatten() returns a view, not a copy

Bflatten is not called as a method

Carr is not a NumPy array

Dprint syntax is incorrect

Step-by-Step Solution

Solution:

Step 1: Identify method call mistake
The code assigns flat = arr.flatten without parentheses, so flat is a method, not the flattened array.
Step 2: Correct usage
Trying to index flat[0] fails because flat is a method object, not an array. Use arr.flatten() directly.
Final Answer:
flatten is not called as a method when assigned. -> Option B
Quick Check:
Method must be called with () to execute [OK]

Quick Trick: Always use parentheses to call methods [OK]
