Python入门练习,Question 2: buyLotsOfFruit function
Add a buyLotsOfFruit(orderList) function to buyLotsOfFruit.py which takes a list of (fruit,pound) tuples and returns the cost of your list. If there is some fruit in the list which doesn t appear in fruitPrices it should print an error message and return None. Please do not change the fruitPrices variable.
Run python autograder.py until question 2 passes all tests and you get full marks. Each test will confirm that buyLotsOfFruit(orderList) returns the correct answer given various possible inputs. For example, test_cases/q2/food_price1.test tests whether:
Cost of [( apples , 2.0), ( pears , 3.0), ( limes , 4.0)] is 12.25
