断言 inputList == inputListSorted

Question

你能帮我吗，我的代码有什么问题吗？

def generalized_price_sorter_expensive_cheap_assert(inputList, typeOfSort):
    #print(inputList)
    if typeOfSort == "cheap":
        inputListSorted = inputList.copy()
        inputListSorted.sort()


        if inputList == inputListSorted:  ##compare first list to second list, if is equal = good
            print("Cheap sorter is OK")

        else:
            print("Cheap sorter is NOT OK")

    if typeOfSort == "expensive":
        inputListSorted = inputList.copy()
        inputListSorted.sort(reverse=True)
        if inputList == inputListSorted:
            print("Expensive sorter is OK")
        else:
            print("Expensive sorter is NOT OK")

    print("LIST FROM WEB:")
    print(inputList)
    print("CORRECTLY SORTED LIST")
    print(inputListSorted)

    assert inputList == inputListSorted

我的断言错误：

Answer 1

您需要将排序后的列表分配给变量，因为排序未到位。

inputListSorted = inputList.copy()
inputListSorted = sorted(inputListSorted)

# Or in a single line

inputListSorted = sorted(inputList.copy())

Answer 2

您收到断言错误，因为列表之间的元素顺序不同。如果您想检查两个列表是否具有相同的元素，您可以这样做：

import collections

def assert_same_elements(left, right):
    assert collections.Counter(left) == collections.Counter(right)

list_from_web = [
    14818, 13398, 12958, 12138, 12058, 11038, 12178, 11938,
    12018, 11238, 11178, 11498, 10478, 11378, 11558, 10838,
    11318, 11858, 11458, 10938
]

correctly_sorted_list = [
    14818, 13398, 12958, 12178, 12138, 12058, 12018, 11938,
    11858, 11558, 11498, 11458, 11378, 11318, 11238, 11178,
    11038, 10938, 10838, 10478
]

assert_same_elements(list_from_web, correctly_sorted_list)
