NumPy - Array Operations
Identify the error in the following code snippet:
import numpy as np
arr = np.array([True, False, True])
result = arr and np.array([False, True, False])
print(result)
Anp.array should be np.logical_and
BUsing 'and' operator directly on NumPy arrays causes an error
CMissing parentheses around arrays
DArrays must be converted to lists before logical operations
Step-by-Step Solution
Solution:
  1. Step 1: Understand Python 'and' operator with arrays

    'and' is a Python keyword that does not work element-wise on arrays; it expects single boolean values.
  2. Step 2: Identify correct way to do element-wise logical AND

    Use numpy.logical_and(arr1, arr2) for element-wise AND on arrays.
  3. Final Answer:

    Using 'and' operator directly on NumPy arrays causes an error -> Option B
  4. Quick Check:

    Python 'and' fails on arrays; use logical_and [OK]
Quick Trick: Use numpy.logical_and, not Python 'and' for arrays [OK]
Common Mistakes:
  • Using Python 'and' instead of numpy.logical_and
  • Trying to use 'and' without parentheses
  • Converting arrays to lists unnecessarily
