REST is the most used mechanism to publish APIs for general consumption. Each language has its own set of libraries and methods that help a developer consume these APIs. This course will teach you how to use Python and its libraries for consuming and creating REST APIs in the easiest way possible.

In the first part of this course, you’ll learn how to work with Python in using REST APIs for various scenarios. Then, in the second part, you’ll focus on building your own REST APIs using the HTTP methods, including GET, PUT, etc.

This course is geared toward intermediate users who have a basic understanding of Python and want to improve their skills in using existing REST APIs and building their REST API implementations.

Python REST API Development: A Comprehensive Guide

In a REST API, GET can be used to either retrieve the whole collection of resources or a specific item from the collection. In this lesson, we'll look at how to implement an API that will return a product based on the product ID passed as a path parameter.

Flask provides an easy way to map the path parameter of the URI to the parameter of the method that handles the request for that URI. Without further ado, let's implement the API endpoint that returns a specific product.




# Steps

1. Open `server/api/products_api.py`.

2. Add a new method that accepts a parameter named `product_id`. Name the method `get_product`.
```python
def get_product(product_id):
```

3. Add the following code to the `get_product` method.
```python
      result = next((product for product in products if product['id'] == product_id), None)
	return jsonify(result)
```

4. Decorate the method with the `route` decorator of `products_blueprint`. Pass the URI that will represent the endpoint and the supported HTTP method, which is `GET`. Add the path parameter named `product_id` to the URI.
```python
@products_blueprint.route('/products/<product_id>', methods=['GET'])
```

5. Run the application.

6. Hit the following URL using your preferred tool. When testing on the Educative platform, please replace `http://localhost` with the URL provided in the SPA widget.
```
$curl http://localhost:5000/api/products/1
```

7. The following output should be obtained.
```json
{
  "description": "container for servlet",
  "id": "1",
  "name": "servlet-container",
  "version": "3.0"
}
```
