NumPy - Array Operations
Identify the potential issue in this code:
import numpy as np
arr = np.array([True, False, True])
result = np.logical_not(arr, out=arr)
print(result)
AUsing the same array as output causes unexpected results
Bnp.logical_not does not accept an 'out' parameter
CThe array must be of integers, not booleans
Dnp.logical_not requires two input arrays
Step-by-Step Solution
Solution:
  1. Step 1: Check use of 'out' parameter

    Using the same array as input and output can overwrite data during computation, causing unexpected results.
  2. Step 2: Proper usage

    Use a different array or omit 'out' to avoid overwriting input during operation.
  3. Final Answer:

    Using the same array as output causes unexpected results -> Option A
  4. Quick Check:

    Same input/output array in logical_not = Risky [OK]
Quick Trick: Avoid using same array as input and output [OK]
Common Mistakes:
  • Overwriting input array
  • Assuming 'out' is not supported
  • Confusing input types
