To-Do List App Python Code

# To-Do List App in Python
# This project helps students manage daily tasks

# Empty list to store tasks
tasks = []


# Function to add a new task
def add_task():
    task = input("Enter your task: ")
    tasks.append(task)
    print("Task added successfully!")


# Function to view all tasks
def view_tasks():
    if len(tasks) == 0:
        print("No tasks available.")
    else:
        print("\nYour Tasks:")
        for index, task in enumerate(tasks, start=1):
            print(index, ".", task)


# Function to delete a task
def delete_task():
    view_tasks()

    if len(tasks) == 0:
        return

    task_number = int(input("Enter task number to delete: "))

    if 1 <= task_number <= len(tasks):
        removed_task = tasks.pop(task_number - 1)
        print("Deleted task:", removed_task)
    else:
        print("Invalid task number!")


# Main program loop
while True:
    print("\n===== To-Do List App =====")
    print("1. Add Task")
    print("2. View Tasks")
    print("3. Delete Task")
    print("4. Exit")

    choice = input("Enter your choice: ")

    if choice == "1":
        add_task()

    elif choice == "2":
        view_tasks()

    elif choice == "3":
        delete_task()

    elif choice == "4":
        print("Thank you for using To-Do List App!")
        break

    else:
        print("Invalid choice! Please try again.")

How the Program Works

Steps

1.The program creates an empty list:

tasks = []

2.The user can add tasks.

Example:

Enter your task: Do homework
Task added successfully!

3.The user can view all tasks.

Example:

Your Tasks:
1. Do homework
2. Read a book

4.The user can delete a task by task number.

Example:

Enter task number to delete: 1
Deleted task: Do homework

How to Run the Program

Steps
1. Create Python File

Create a file named:

todo_list_app.py

2.Paste the Code

Copy the above code and paste it inside the file.

3.Run the Program

Open terminal and run:

python todo_list_app.py

To-Do List App Using Python Tkinter UI

# Import tkinter module
import tkinter as tk
from tkinter import messagebox

# Create main window
root = tk.Tk()

# Window title
root.title("To-Do List App")

# Window size
root.geometry("500x500")

# Background color
root.config(bg="#f0f8ff")

# List to store tasks
tasks = []


# Function to add task
def add_task():

    # Get task from input box
    task = task_entry.get()

    # Check if input is empty
    if task == "":
        messagebox.showwarning("Warning", "Please enter a task!")
    else:

        # Add task to list
        tasks.append(task)

        # Add task to listbox
        task_listbox.insert(tk.END, task)

        # Clear input box
        task_entry.delete(0, tk.END)


# Function to delete selected task
def delete_task():

    try:

        # Get selected task index
        selected_task = task_listbox.curselection()[0]

        # Remove task from listbox
        task_listbox.delete(selected_task)

        # Remove task from list
        tasks.pop(selected_task)

    except:
        messagebox.showwarning("Warning", "Please select a task to delete!")


# Function to clear all tasks
def clear_tasks():

    # Clear listbox
    task_listbox.delete(0, tk.END)

    # Clear task list
    tasks.clear()


# Heading label
title_label = tk.Label(
    root,
    text="To-Do List App",
    font=("Arial", 22, "bold"),
    bg="#f0f8ff",
    fg="#1e3a8a"
)

title_label.pack(pady=20)


# Input box
task_entry = tk.Entry(
    root,
    font=("Arial", 14),
    width=30
)

task_entry.pack(pady=10)


# Add Task Button
add_button = tk.Button(
    root,
    text="Add Task",
    font=("Arial", 12, "bold"),
    bg="#2563eb",
    fg="white",
    padx=20,
    pady=5,
    command=add_task
)

add_button.pack(pady=5)


# Delete Task Button
delete_button = tk.Button(
    root,
    text="Delete Task",
    font=("Arial", 12, "bold"),
    bg="#dc2626",
    fg="white",
    padx=20,
    pady=5,
    command=delete_task
)

delete_button.pack(pady=5)


# Clear All Button
clear_button = tk.Button(
    root,
    text="Clear All",
    font=("Arial", 12, "bold"),
    bg="#16a34a",
    fg="white",
    padx=20,
    pady=5,
    command=clear_tasks
)

clear_button.pack(pady=5)


# Listbox to display tasks
task_listbox = tk.Listbox(
    root,
    font=("Arial", 14),
    width=35,
    height=10
)

task_listbox.pack(pady=20)


# Run the window
root.mainloop()

Output Screens:
1. Add Task


2. Delete Task

3. Clear All


How the Program Works

Steps

1.The program opens a Tkinter window.

2.The student enters a task.

Example:

Do Homework

3.Click Add Task.

The task is added to the list.

4.Select a task and click Delete Task to remove it.

5.Click Clear All to remove all tasks.
