为什么我们得不到正确的输出？ [英] Why dont we get the right output?

问题描述

我们正在以四人一组的方式工作，并且花了最后几个小时来调试/修复我们的代码以获得正确的输出。您将在下面找到我们的代码，其中包含字符串所在的列表和所需的输出。请帮忙。



我们的代码是：

We are working in a group of four and have spent the last few hours tring to debug/fix our code to get the right output. Below you will find our code the list in which the string is in and required output. Please help.

Our code is:

def reverse(my_list, number):    
    string = ""
    new_list = []
    count = 0

    if number > len(my_list):
        number = len(my_list)
    if number < 2:
        for k in my_list:
            new_list.append(k)
        return my_list

    for index in range(number-1,-1,-1):
        new_list.append(my_list[index])

    for index in range (number, len(my_list)):
        new_list.append(my_list[index])

    return new_list

list其中包含字符串：

list in which string is in:

print("\nreverse Test")
str_list6 = ['e', 'd', 'u', 'd']
str_list7 = ['m', 'o', 'b', 'b', 'e', 'd']
new_list = list_function.reverse(str_list6, 4)
print(new_list)
new_list = list_function.reverse(str_list7, 3)
print(new_list)
new_list = list_function.reverse(str_list6)
print(new_list)

必填输出是：

Required output is:

reverse Test
['d', 'u', 'd', 'e']
['b', 'o', 'm', 'b', 'e', 'd']
['d', 'u', 'd', 'e']

推荐答案

试试这个：

Try this:

def reverse(my_list, number = 0):
    newlist = []
    if number == 0:
        number = len(my_list)
    for x in range(number-1, -1, -1):
        newlist.append(my_list[x])
    for x in range(number, len(my_list)):
        newlist.append(my_list[x])
    return newlist
