learn python with this one project: a simple to-do list application

in this tutorial, we'll learn python by building a simple command-line to-do list application. this project will cover basic concepts such as functions, lists, loops, and user input, making it perfect for beginners.

project overview

the to-do list application will allow users to:
view their current tasks
add new tasks
remove completed tasks
exit the application

prerequisites

before we start, ensure you have python installed on your computer. you can download it from [python.org](https://www.python.org/downloads/).

step 1: setting up the project

create a new directory for your project and create a file named `todo_list.py`.



step 2: writing the code

open `todo_list.py` in your favorite text editor. we'll start by defining the main functionality of our application.

code example

here's the complete code for our to-do list application:



code explanation

1. **function definitions**:
`display_tasks(tasks)`: displays the current list of tasks. if the list is empty, it informs the user.
`add_task(tasks)`: prompts the user to enter a new task and adds it to the list.
`remove_task(tasks)`: displays the list of tasks, asks the user for a task number, and removes the specified task if valid.

2. **main function**:
the `main()` function initializes an empty task list and enters a loop that presents the user with options to view, add, remove tasks, or exit the application.

3. **user interaction**:
the application continuously prompts the user for input until they choose to exit.

step 3: running your application

to run your to-do list application, open your terminal, navigate to the project directory, and execute the following command:



step 4: testing your application

once the application is running, test its functionality:
add some tasks and verify they appear in the list.
remove a task and check that it's no longer listed.
