Question

Check if a list is a palindrome. Instructions:

- Create a file named palin.py and create a function inside called palindrome.
- The function palindrome should take in a list as input.
- The function should return a boolean (True or False), depending on whether the list is a palindrome.
- Your function can assume a list will be inputted. - You can not use the Python function reverse().
- When you submit, do not have any code that calls palindrome nor should it have any print statements. Our code will take care of calling your function.
- Be mindful of various list sizes when thinking about how to handle bad input. Examples:
Input : [1, 2, "Espresso", "Madeline", 2, 1]
Output: False
Input: ['a', True, False, False, True, 'a']
Output: True Input : [3]

Answer 1

To check if a list is a palindrome, manually reverse the list using a loop and compare it with the original list.

Step-by-step explanation:

The subject of this question is Computers and Technology and the grade level is High School.

To check if a list is a palindrome, we can compare the elements at corresponding positions in the list. If the list is equal to its reverse, then it is a palindrome. However, since the instructions state that we cannot use the Python function reverse(), we can manually reverse the list using a loop and compare it with the original list.

Here's an example implementation of the palindrome function:

def palindrome(lst):
reversed_lst = []
for i in range(len(lst)-1, -1, -1):
reversed_lst.append(lst[i])
return lst == reversed_lst
