如何比较两个不同长度的列表并删除一些元素？

def compare_and_delete(list1, list2):
    if len(list1) > len(list2):
        longer_list = list1
        shorter_list = list2
    else:
        longer_list = list2
        shorter_list = list1

    for i in range(len(shorter_list)):
        if longer_list[i] == shorter_list[i]:
            longer_list.remove(longer_list[i])

    return longer_list

# 示例使用
list1 = [1, 2, 3, 4, 5, 6]
list2 = [1, 2, 4]
result = compare_and_delete(list1, list2)
print(result)
