easy📝 Conceptual Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall correct reshape syntax
The correct syntax isarray.reshape(dim1, dim2, ...)with dimensions as separate arguments or a tuple.Step 2: Evaluate options
arr.reshape(2, 3) uses correct method call with separate arguments. arr.reshape(2[3]) has invalid syntax (missing comma). arr.reshape{2, 3} uses curly braces which is wrong syntax. reshape(arr, 2, 3) uses a function call without object which is invalid.Final Answer:
arr.reshape(2, 3) -> Option CQuick Check:
Use dot and parentheses with dims [OK]
Quick Trick: Use dot and parentheses with dims, no brackets [OK]
Common Mistakes:
- Forgetting comma between dimensions
- Using curly braces instead of parentheses
- Calling reshape as a standalone function
