Project 0: Python, Setup, & Autograder Tutorial

Project 食用教程，类似 CS61A，可以本地测试，可以在 Gradescope 实测（这个 Proj 除外）

给了三道试机题，解答如下（谁家 one-liner）

addition.py

def add(a, b):
    "Return the sum of a and b"
    "*** YOUR CODE HERE ***"
    return a + b

def buyLotsOfFruit(orderList):
    """
        orderList: List of (fruit, numPounds) tuples

    Returns cost of order
    """
    "*** YOUR CODE HERE ***"
    return sum(fruitPrices[fruit] * numPounds for fruit, numPounds in orderList)
shopSmart.py

def shopSmart(orderList, fruitShops):
    """
        orderList: List of (fruit, numPound) tuples
        fruitShops: List of FruitShops
    """
    "*** YOUR CODE HERE ***"
    # shop.py 中有一些函数实现，比如 getPriceOfOrder()
    return min(fruitShops, key=lambda shop: shop.getPriceOfOrder(orderList))

本地 python autograder.py 的结果
