Python Coding challenge - Day 69 | What is the output of the following Python code?

 

The above code of the list my_list using slicing and assigns a new set of values [7, 8, 9] to the sliced portion. Here's a step-by-step breakdown:

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

This initializes a list with the values [1, 2, 3, 4, 5].

my_list[1:3] = [7, 8, 9]

This slices the elements at index 1 and 2 (exclusive) of my_list and replaces them with the values [7, 8, 9]. After this line executes, my_list becomes [1, 7, 8, 9, 4, 5].

print(my_list)

This prints the modified list:

[1, 7, 8, 9, 4, 5]

So, the final output is [1, 7, 8, 9, 4, 5].
