Flask Todo App: Step-by-Step Tutorial

Flask is a popular web development framework written in Python. In this tutorial, we will guide you through the process of building a simple Todo App using Flask. The tutorial will be conducted in Hindi, so it is perfect for those who are more comfortable with the language.

Step 1: Setup

First, make sure you have Python and Flask installed on your system. If not, you can easily install them by following the official documentation.

Step 2: Create a new Flask app

Open your terminal or command prompt and create a new directory for your Flask app. Inside the directory, create a new Python file called app.py. This will be the main file for your Flask app.

Step 3: Define routes

In your app.py file, define the routes for your Todo App. For example, you can have routes for displaying the list of todos, adding a new todo, marking a todo as completed, and deleting a todo.

Step 4: Create templates

Create HTML templates for your Todo App. You can use the Jinja templating engine to dynamically render data in your templates. For example, you can create a template for displaying the list of todos, and another template for adding a new todo.

Step 5: Implement functionality

In your app.py file, implement the functionality for adding, completing, and deleting todos. This may involve interacting with a database, such as SQLite, to store and retrieve todos.

Step 6: Run your Flask app

Once everything is set up, you can run your Flask app and test it in a web browser. Make sure to handle any potential errors and make necessary adjustments to your code.
