Python Coding challenge - Day 84 | What is the output of the following Python Code?

 



Code :

my_list = [1, 2, 3, 4, 5] 

result = my_list[1:4:2] 

print(result)

Solution and Explanation : 

Let's break down the code:

my_list = [1, 2, 3, 4, 5]
Here, you have defined a list named my_list containing the elements 1, 2, 3, 4, and 5.

result = my_list[1:4:2]
This line uses slicing to create a new list named result from my_list. The slicing syntax is start:stop:step. In this case:

start is 1
stop is 4 (exclusive, so it includes elements at indices 1 and 2)
step is 2
So, it starts at index 1, includes elements at indices 1 and 3 (skipping every other element because of the step), and stops before index 4.

Therefore, the result will be [2, 4].

print(result)
This line prints the value of result, which is [2, 4].
