Rewriting a Question with Examples in Docstring for APISpec

What will you learn?

In this tutorial, you will master the art of enhancing API documentation by adding exemplary content through docstrings to APISpec in Python. You’ll understand how to provide clear examples within your codebase, making it easier for developers to interact with your API efficiently.

Introduction to the Problem and Solution

When it comes to documenting APIs, clarity is key. Providing explicit examples of how endpoints should be utilized is crucial for developers. One effective method to achieve this is by embedding examples directly into the code using docstrings. This approach not only simplifies the understanding of API functionality but also reduces the need for extensive external documentation.

In this tutorial, we delve into leveraging docstrings and APISpec in Python to seamlessly integrate illustrative examples that showcase the functionality of our API endpoints effectively.


from apispec import APISpec

spec = APISpec(
    title='Swagger Petstore',

class PetResource:
    def get(self, pet_id):
        """Get pet details by ID.
          - name: pet_id
            in: path
            type: integer
            required: true
            description: The ID of the pet.
            description: Details of the requested pet.
             name: fluffy
             age: 5

To enrich your API documentation with examples using docstrings within APISpec, follow these steps:

  1. Import Necessary Modules: Import APISpec from apispec.
  2. Initialize APISpec: Create an instance of APISpec with relevant details such as title and version.
  3. Add Examples in Docstring: Utilize triple quotes (“””) within your resource class or method for multi-line strings as a docstring.
  4. Utilize YAML-like Format: Define input parameters, responses, and examples following YAML-like syntax inside the docstring.
  5. Include Example Values: Provide example values for parameters and response bodies.

By structuring your docstrings according to the OpenAPI Specification (OAS), you can effectively document your API while offering concrete examples for developers consuming the API.

    How do I install APISpec in Python?

    To install APISpec using pip, run pip install apispe.

    Can I include multiple examples for different scenarios in one docstring?

    Yes, you can include multiple examples within a single docstring by appropriately separating them using YAML syntax.

    Is it necessary to follow a specific format when writing examples in docstrings?

    It’s recommended to adhere to structured formats like YAML or JSON when including examples in docstrings for better readability and consistency.

    Are there any tools available for generating API documentation from code with embedded examples?

    Yes, tools like Swagger UI or Redoc can parse your codebase containing embedded example snippets and automatically generate interactive API documentation.

    How often should I update my embedded examples within code documentation?

    It’s good practice to keep your embedded examples up-to-date whenever there are changes made to endpoint functionalities or request/response structures.


    Enhancing your API documentation with detailed and concise exemplary content via well-crafted inline documented snippets significantly improves comprehension levels among users interacting across various endpoints. By integrating meticulous exemplary content seamlessly into burgeoning projects, you elevate user experiences manifoldly!
