STEP 1

Gather some knowledge.

The function can go through the list, add the numbers and return the result.

def total(prices):
    result = 0
    for price in prices:
        result = result + price
    return result

✦ So far, the function has just been created.

STEP 2

Hand over the list and show the results.

Create a list of prices, transfer its functions and output the received answer.

prices = [2, 3]
print(total(prices))

✦ If the function from the first step is already created, the answer will be 5.

IN-CLASS PRACTICE
