    "Go to School",
    "Come Back from school",
    "Do Homework",
    "Eat Dinner",
    "Brush my Teeth",
    "And then sleep"

# Function to display tasks with indices
def display_tasks():
    print("Your To-Do List:")
    for index in range(len(tasks)):
        print(f"{index + 1}. {tasks[index]}")  # Display task with its index

# Call the function
display_tasks()
