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:

Python

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 in which string is in:

Python

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)

Required output is:

Python

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

The input parameters suggest that you take the length parameter and reverse that number of characters, and then append the remainder. If there is no length parameter then take the length of the list.

Try this:

Python

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
