Array Deletion at End in DSA Python - Build from Scratch

Array Deletion at End

📖 Scenario: You are managing a list of tasks to do today. Sometimes, you finish the last task and want to remove it from your list.

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

📋 What You'll Learn

Create a list called tasks with these exact items: 'Laundry', 'Dishes', 'Homework', 'Exercise'

Create a variable called last_task that removes the last item from the tasks list

Print the updated tasks list after removing the last task

💡 Why This Matters

🌍 Real World

Managing daily to-do lists or any ordered collection where you often remove the last item, like undo stacks or recent files.

💼 Career

Understanding list operations like removing items from the end is fundamental for programming tasks in software development, data processing, and automation.

1

Create the initial list of tasks

Create a list called tasks with these exact items in order: 'Laundry', 'Dishes', 'Homework', 'Exercise'

DSA Python

# Create the list of tasks
# Your code here

Hint

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

2

Remove the last task from the list

Create a variable called last_task that removes the last item from the tasks list using the pop() method

DSA Python

tasks = ['Laundry', 'Dishes', 'Homework', 'Exercise']
# Remove the last task and store it in last_task
# Your code here

Hint

The pop() method removes the last item from a list and returns it.

3

Print the updated list of tasks

Print the tasks list to show the tasks remaining after removing the last one

DSA Python

tasks = ['Laundry', 'Dishes', 'Homework', 'Exercise']
last_task = tasks.pop()
# Print the updated tasks list
# Your code here

Hint

Use print(tasks) to display the list.

4

Print the removed last task

Print the variable last_task to show which task was removed from the end

DSA Python

tasks = ['Laundry', 'Dishes', 'Homework', 'Exercise']
last_task = tasks.pop()
print(tasks)
# Print the removed last task
# Your code here

Hint

Use print(last_task) to show the removed task.
