arr?Which of the following is the correct NumPy function syntax to find the maximum value in a NumPy array named arr?
easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Identify correct function usage
The functionnp.max(arr)correctly finds the maximum value in the arrayarr.Step 2: Analyze other options
arr.max() is valid but uses method syntax, not function syntax. np.maximum(arr) is incorrect becausenp.maximum()compares two arrays element-wise. max(arr) is Python's built-in max, which works on lists but not efficiently on NumPy arrays.Final Answer:
np.max(arr) -> Option BQuick Check:
np.max(arr) = max value [OK]
Quick Trick: Use np.max(array) to get max value quickly [OK]
Common Mistakes:
- Using np.maximum() instead of np.max()
- Confusing method and function syntax
- Using Python max() on NumPy arrays
