NumPy - Array Manipulation

You have a 1D NumPy array of 24 elements representing hourly temperature readings for one day. How would you reshape it to represent 4 weeks of data with 6 days each, assuming 1 reading per hour per day?

Aarr.reshape(6, 4, 24)

Barr.reshape(4, 6, 24)

Carr.reshape(4, 6, 1)

Darr.reshape(24, 4, 6)

Step-by-Step Solution

Solution:

Step 1: Understand data structure
24 elements represent 24 hours in a day.
Step 2: Calculate total elements for 4 weeks and 6 days
4 weeks * 6 days * 24 hours = 576 elements needed, but original array has only 24 elements.
Step 3: Check options for logical reshape
Only arr.reshape(4, 6, 1) reshapes to 24 elements total (4*6*1=24), matching original array size.
Final Answer:
arr.reshape(4, 6, 1) -> Option C
Quick Check:
Reshape matches total elements [OK]

Quick Trick: Match reshape dims to total elements [OK]

Common Mistakes:

Ignoring total elements needed
Mixing up dimension order
