easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Review vectorized addition syntax
NumPy supports element-wise addition directly withc = a + b.Step 2: Check other options
for i in range(len(a)): c[i] = a[i] + b[i]uses a loop (not vectorized),np.add(a, b, out=None, where=False)has wrong parameters,c = a.append(b)is invalid for arrays.Final Answer:
c = a + b -> Option CQuick Check:
Use+for vectorized array addition [OK]
Quick Trick: Use
c = a + b for fast element-wise addition [OK]Common Mistakes:
- Using loops instead of vectorized operators
- Misusing np.add with wrong parameters
- Trying to append arrays for addition
