Creating a RESTful API with Flask

Introduction:

• Brief overview of RESTful APIs.
• Why Flask is a popular choice for building APIs.

Step 1: Setting Up Flask Project:

1. Install Flask using pip.

pip install flask

1. Create a new Flask project directory.

Step 2: Building the API Structure:

1. Create the main Flask application file (app.py).
2. Define routes for different API endpoints (GET, POST, PUT, DELETE).

Step 3: Implementing CRUD Operations:

Endpoint 1: Retrieving Data

1. Create a route to retrieve all data.
2. Implement a function to handle the GET request.

Endpoint 2: Adding Data

1. Set up a route to add new data.
2. Implement a function to handle the POST request.

Endpoint 3: Updating Data

1. Define a route for updating existing data.
2. Implement a function to handle the PUT request.

Endpoint 4: Deleting Data

1. Create a route for deleting data.
2. Implement a function to handle the DELETE request.

Step 4: Testing the API:

1. Install Postman for API testing.
2. Create requests for each CRUD operation.
3. Test the API locally.

Conclusion:

1. Recap the key steps.
2. Emphasize the importance of testing and documentation.
