Array Insertion at Middle Index in DSA Python - Build from Scratch

Array Insertion at Middle Index

📖 Scenario: You are managing a list of daily tasks. Sometimes, you want to add a new task right in the middle of your current list to keep things balanced.

🎯 Goal: Learn how to insert a new item exactly in the middle of an existing list (array) in Python.

📋 What You'll Learn

Create a list called tasks with specific task names

Create a variable called new_task with a given task name

Insert new_task into the middle index of tasks

Print the updated tasks list

💡 Why This Matters

🌍 Real World

In daily task management apps, inserting tasks in the middle helps keep the schedule balanced and organized.

💼 Career

Understanding list operations like insertion is essential for software developers working with data collections and user interfaces.

1

Create the initial list of tasks

Create a list called tasks with these exact strings in order: 'Email', 'Meeting', 'Coding', 'Review', 'Deploy'

DSA Python

# Create the list called tasks with the given tasks
# Your code here

Hint

Use square brackets [] to create a list and separate items with commas.

2

Create the new task to insert

Create a variable called new_task and set it to the string 'Lunch Break'

DSA Python

tasks = ['Email', 'Meeting', 'Coding', 'Review', 'Deploy']
# Create the variable new_task with value 'Lunch Break'
# Your code here

Hint

Use the assignment operator = to set the variable.

3

Insert the new task in the middle

Calculate the middle index of tasks using len(tasks) // 2 and insert new_task at that index using tasks.insert()

DSA Python

tasks = ['Email', 'Meeting', 'Coding', 'Review', 'Deploy']
new_task = 'Lunch Break'
# Insert new_task into the middle index of tasks
# Your code here

Hint

Use len() to get the list length and insert() to add the item.

4

Print the updated tasks list

Print the tasks list to show the new order after insertion

DSA Python

tasks = ['Email', 'Meeting', 'Coding', 'Review', 'Deploy']
new_task = 'Lunch Break'
middle_index = len(tasks) // 2
tasks.insert(middle_index, new_task)
# Print the tasks list
# Your code here

Hint

Use print(tasks) to display the list.
