- Why Flask is a popular choice for building APIs.
Step 1: Setting Up Flask Project:

- Define routes for different API endpoints (GET, POST, PUT, DELETE).
Step 3: Implementing CRUD Operations:
Endpoint 1: Retrieving Data
- Create a route to retrieve all data.
- Implement a function to handle the GET request.
Endpoint 2: Adding Data

- Implement a function to handle the POST request.
Endpoint 3: Updating Data
- Define a route for updating existing data.
- Implement a function to handle the PUT request.
Endpoint 4: Deleting Data
- Create a route for deleting data.
- Implement a function to handle the DELETE request.
Step 4: Testing the API:
- Install Postman for API testing.
- Create requests for each CRUD operation.
- Test the API locally.
Conclusion:
- Recap the key steps.
- Emphasize the importance of testing and documentation.
