Average Value
The arithmetic mean helps you quickly understand a typical value in a list, such as an average score, price, or time. Write a function mean that adds all numbers in nums and divides the sum by the number of items. If the list is empty, return 0 to avoid division by zero. Use ordinary division, so the result may be fractional.
