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

Array Deletion at Middle Index

📖 Scenario: You are managing a list of daily tasks. Sometimes, you need to remove the task that is exactly in the middle of your list to keep your schedule balanced.

🎯 Goal: Build a program that creates a list of tasks, finds the middle task, removes it, and then shows the updated list.

📋 What You'll Learn

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

Create a variable called middle_index that holds the middle index of the tasks list

Remove the task at middle_index from the tasks list

Print the updated tasks list

💡 Why This Matters

🌍 Real World

Managing daily tasks or schedules often requires removing or updating items in the middle to keep balance.

💼 Career

Understanding list operations like finding indexes and deleting items is essential for data manipulation in many programming jobs.

1

Create the list of tasks

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

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

Find the middle index

Create a variable called middle_index that holds the middle index of the tasks list using integer division

DSA Python

tasks = ['Email', 'Meeting', 'Coding', 'Review', 'Lunch']
# Calculate the middle index of tasks
# Your code here

Hint

Use len(tasks) to get the number of tasks and // for integer division.

3

Remove the middle task

Remove the task at middle_index from the tasks list using the del statement

DSA Python

tasks = ['Email', 'Meeting', 'Coding', 'Review', 'Lunch']
middle_index = len(tasks) // 2
# Remove the middle task from tasks
# Your code here

Hint

Use del tasks[middle_index] to remove the item at the middle index.

4

Print the updated list

Print the updated tasks list using print(tasks)

DSA Python

tasks = ['Email', 'Meeting', 'Coding', 'Review', 'Lunch']
middle_index = len(tasks) // 2
del tasks[middle_index]
# Print the updated tasks list
# Your code here

Hint

Use print(tasks) to show the list after removal.
