Python Coding challenge - Day 85 | What is the output of the following Python Code?

 





Let's break down the code:

my_list = [60, 70, 80, 90, 100]

result = my_list[4::-1]

print(result)

In this code, my_list is a list containing the elements [60, 70, 80, 90, 100]. The expression my_list[4::-1] is a slicing operation with the following parameters:


4 is the starting index, and it starts from the last element (index 4).

:: indicates the slicing with a step of -1, which means it goes backward.

So, my_list[4::-1] will start from index 4 and go backward with a step of 1, including the element at index 4 itself. Therefore, it will select elements in reverse order.


The result will be a new list containing the elements [100, 90, 80, 70, 60]. When you print the result, you'll get:

[100, 90, 80, 70, 60]
