Array Deletion at Beginning

📋 What You'll Learn

💡 Why This Matters

🌍 Real World

Managing daily tasks or to-do lists often requires removing completed tasks from the beginning to focus on the next ones.

💼 Career

Understanding how to manipulate lists by removing items is a basic skill useful in data processing, user interface updates, and many programming tasks.

1

Create the initial list of tasks

Create a list called tasks with these exact values in order: 'Wake up', 'Brush teeth', 'Eat breakfast', 'Go to work'

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

Store the first task before deletion

Create a variable called first_task and set it to the first item in the tasks list

DSA Python

tasks = ['Wake up', 'Brush teeth', 'Eat breakfast', 'Go to work']
# Store the first task in first_task
# Your code here

Hint

Use tasks[0] to get the first item from the list.

3

Remove the first task from the list

Remove the first item from the tasks list using the del statement and index 0

DSA Python

tasks = ['Wake up', 'Brush teeth', 'Eat breakfast', 'Go to work']
first_task = tasks[0]
# Remove the first task from tasks
# Your code here

Hint

Use del tasks[0] to delete the first item from the list.

4

Print the updated list after deletion

Print the tasks list to show its state after removing the first task

DSA Python

tasks = ['Wake up', 'Brush teeth', 'Eat breakfast', 'Go to work']
first_task = tasks[0]
del tasks[0]
# Print the updated tasks list
# Your code here

Hint

Use print(tasks) to display the list.
