Example

Three more built-in tools work on a list of numbers:

sales = [96, 120, 175, 120, 100]
print(sum(sales))
print(min(sales))
print(max(sales))

Output:

611
96
175

sum(sales)Adds up every number in the list.

min(sales)The smallest number.

max(sales)The biggest number.

Put together: sum(sales) / len(sales) is the average: the total divided by how many.

Try each one in your head first, then open the answer.

1. Build a line that shows the total of prices.

print(sum(prices))

2. Build a line that stores the biggest sale in a variable called best.

best = max(sales)

3. Print the total of all the sales.

sales = [96, 120, 175, 120, 100]
print(sum(sales))

4. Print the smallest sale.

sales = [96, 120, 175, 120, 100]
print(min(sales))

5. Print the average sale: the total divided by how many sales there are.

sales = [96, 120, 175, 120, 100]
print(sum(sales) / len(sales))

Learn it by doing. This lesson is a short hands-on level on Bampaa: see it work, then build and write it yourself, with instant feedback.
