如何创建一个搜索两个列表的函数，在列表中缺少项目的地方添加一个占位符，如 ' ' 或 'missing item'？

List1 是完整列表。它有所有的线条。然而，List2 是不完整的列表。它有 list1 中的一些行，但是缺少一些行。 List3 是结果的样子。现在我如何创建一个搜索 List1 和 List2 的函数，当它找到不在 list2 中的行时，插入占位符 ' '，以便在所有内容的末尾，输出正好是 List3。请帮忙

Answer 1

您需要并行检查 list1 和 list2，并且始终有匹配项 - 添加到 list3。如果没有匹配 - 附加占位符并在 list1 中前进。我想应该是这样的：

list_result = []
i = 0
j = 0
while i < len(list1) and j < len(list2):
    if list1[i] == list2[j]:
        list_result.append(list1[i])
        i += 1
        j += 1
    else:
        list_result.append(' ')
        i += 1
diff = len(list1) - len(list_result)
for k in range(diff):
    list_result.append(' ')

Answer 2

您可以尝试关注以获得更具体的答案

def missing_words(list1, list2):
    for i in range(len(list1)):
        if list1[i] != list2[i]:
           list2.insert(i,  ' ')

missing_words(list1, list2)
if list2==list3:
    print("yess")

如何创建一个搜索两个列表的函数，在列表中缺少项目的地方添加一个占位符，如 ' ' 或 'missing item'？

How can I create a function that searches through two lists, adding a placeholder like ' ' or 'missing item' in the list where the item is missing?

python
