Which of these best describes vectorized operations in numpy?

easy📝 Conceptual Q2 of 15
NumPy - Array Operations
Which of these best describes vectorized operations in numpy?
AOperations that only work on scalars
BOperations that require explicit for-loops in Python
COperations that use recursion internally
DOperations applied element-wise without explicit loops
Step-by-Step Solution
Solution:

  1. Step 1: Define vectorized operations

    Vectorized operations apply a function to each element automatically without writing loops.

  2. Step 2: Eliminate incorrect options

    Explicit loops and recursion are not vectorized; scalars alone don't describe vectorization.

  3. Final Answer:

    Operations applied element-wise without explicit loops -> Option D

  4. Quick Check:

    Vectorized = element-wise without loops [OK]
Quick Trick: Vectorized means no manual loops needed [OK]
Common Mistakes:
  • Confusing vectorized with recursion
  • Thinking vectorized needs explicit loops
  • Assuming vectorized only works on single values
