Python Coding challenge - Day 101| What is the output of the following Python Code?

 

Code :

numbers = [12, 5, 8, 13, 4]

Num = numbers[::2]  

print(Num)

Solution and Explanation: 

The expression numbers[::2] is a slicing operation with the following parameters:

The starting index is omitted, so it starts from the beginning of the list.

The stopping index is omitted, so it goes until the end of the list.

The step is 2, which means it selects every second element.

So, numbers[::2] will select elements from the original list with a step of 2. Let's break it down:

Element at index 0: 12

Element at index 2: 8

Element at index 4: 4

Therefore, the result will be a new list containing the elements [12, 8, 4]. When you print the result, you'll get:

[12, 8, 4]
