Why this approach?

Define our input data - a list of numbers to sum and average

Structured Explanation

Overview

Sum all numbers in a list; divide by count for the average.

Analogy

Adding up your grocery bill then finding the average item price.

Step-by-step

total = sum(numbers) (or manual loop).
count = len(numbers).
average = total / count (check count != 0 first).
Return or print both values.

Visual

[1,2,3,4,5] → sum=15, len=5 → average=3.0

Common mistakes

ZeroDivisionError when the list is empty.
Integer division losing decimal: use / not //.

Practice questions

Compute the average exam score for a class.
Find the sum and average of even numbers only.

Complexity	Operations
O(1)	1
O(log n)	3
O(n)	8
O(n log n)	24
O(n²)	64

Challenge

Compute sum and average of scores = [85, 92, 78, 96, 88, 73]. Identify who scored above average.

Hint

Sum all first, divide by count for average. Then filter with a list comprehension.
