Python Coding challenge - Day 233 | What is the output of the following Python Code?

 Let's break down the code and explain what each part does:

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

my_list[1:3] = []

print(my_list)

Step-by-Step Explanation

Create a List:

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

This line initializes a list named my_list with the elements [1, 2, 3, 4, 5].

Slice Assignment:

my_list[1:3] = []

my_list[1:3] is a slice of the list from index 1 to index 3, but not including index 3. In this case, my_list[1:3] refers to the sublist [2, 3].

The assignment my_list[1:3] = [] replaces the slice [2, 3] with an empty list [], effectively removing the elements 2 and 3 from the list.

Print the Modified List:

print(my_list)

This line prints the modified list.

After the slice assignment, my_list is modified to remove the elements at indices 1 and 2 (the elements 2 and 3). The resulting list is:

[1, 4, 5]

Visual Breakdown

Let's visualize the process:

Initial list: [1, 2, 3, 4, 5]

Slice my_list[1:3] refers to [2, 3]

Assigning [] to the slice removes [2, 3]

Resulting list: [1, 4, 5]

Full Code with Output

Here is the complete code along with its output:

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

my_list[1:3] = []

print(my_list)  # Output: [1, 4, 5]

The output is [1, 4, 5], as explained.
