Python Coding challenge - Day 8| What is the output of the following Python Code?

 

Code Explanation:

my_list = [1, 2, 3, 4, 5]

This line creates a list called my_list with the values [1, 2, 3, 4, 5].

result = my_list[1:4:2]

This line uses list slicing with a start, stop, and step.

Start index (1): This tells Python where to start slicing. It starts from index 1, which is the second element in the list (2).

Stop index (4): This tells Python where to stop slicing. It stops just before index 4. So, it will slice up to index 3 (which is the value 4), but does not include index 4 (the element 5).

Step size (2): This tells Python to take every second element between the start and stop indices. In this case, starting at index 1, it will skip every other element. So, it will take:

The element at index 1 (which is 2),

Then skip index 2 (which is 3), and

Take the element at index 3 (which is 4).

Therefore, the sliced list will contain [2, 4].

print(result)

This line prints the resulting sublist, which is [2, 4].

Summary:

You started with the list [1, 2, 3, 4, 5].

Using slicing with a start index of 1, stop index of 4, and a step size of 2, you selected every second element between index 1 and index 3 (inclusive).

The result is the list [2, 4].

Output:

[2, 4]
