While loop statement - Ex15_1

Result all numbers that can be multiplied by 3

Write a Python program that iterate each element in a provided List and check if it can be multiplied by 3, then append it into a new list called results

Code Provided

Expected outcome after your program executed

[ 3, 3, 9, 3, 12, 21 ]

Code Hints

1. elements.append( element )

While loop statement - Ex15_2

Remove all duplicate elements from the list

Write a Python program that iterate each element in a provided List and remove all the duplicate element from the provided list.

Code Provided

Expected outcome after your program executed

[ 3, 2, 5, 10, 1 ]

Code Hints

2. element in elements

1. elements.append( element )

While loop statement - Ex15_3

Ralindrome Validation

Given a list elements, write a Python code snippet to check if the list is a palindrome. A list is considered a palindrome if it reads the same backward as forward. Your code should output `True` if the list is a palindrome, and `False` otherwise.

Examples

1. For elements = [1, 2, 3, 2, 1], the output should be `True`.
2. For elements = ['a', 'b', 'b', 'a'], the output should be `True`.
3. For elements = [1, 2, 3, 4, 5], the output should be `False`.
4. For elements = [], the output should be `True`.
5. For elements = [42], the output should be `True`.
