Write api with python

Creating and exposing APIs allows your web application to interact with other applications through machine-to-machine communication. Django REST framework continues to knock out great releases after the 3.

Write api with python

For developers utilizing the API, this usually involves making some HTTP requests to the service, and using the responses in their applications. Furthermore, when a part of the API changes, you have to edit all the individual requests you have written.

These libraries also have the advantage of returning data as familiar data structures provided by the language, hence enabling idiomatic ways to access and manipulate this data. By the end of this tutorial, you will learn: How to create and test a custom library which communicates with a third-party API and How to use the custom library in a Python script.

Prerequisites Before we get started, ensure you have one of the following Python versions installed: Project Setup We will organize our project as follows: Our project will be organized around the functionality we expect to provide in our wrapper.

For example, methods related to TV functionality will be in the tv. We need to list our dependencies in the requirements. At the time of writing, these are the latest versions. Update the version numbers if later versions have been published by the time you are reading this.

To run the test, execute the py. As expected, the test will fail with an error message that should contain something similar to the following snippet: This is because the tmdbwrapper package is empty right now. From now on, we will write the package as we go, adding new code to fix the failing tests, adding more tests and repeating the process until we have all the functionality we need.

You should now see the following error message: We seem to be making some progress. Reading through the error, we can see that it occurs when we try to instantiate the TV class with a number.

Therefore, what we need to do next is implement a constructor for the TV class that takes a number. We should see the following error message now: To make this pass, we need to make the info method return a dictionary.

To do this, we have to store the ID as an instance variable, in order to access it from the info function. Writing Foolproof Tests You may be asking yourself why the tests are passing, since we clearly have not fetched any info from the API.

Our tests were not exhaustive enough.

We need to actually ensure that the correct info that has been fetched from the API is returned. We can add a test to check that the correct fields are returned in the response, and this would in turn help us ensure that our tests are indeed checking for a correct response object back from the info method.

For this case, we will select a handful of these properties and ensure that they are in the response. We will use pytest fixtures for setting up the list of keys we expect to be included in the response.

Our test will now look as follows: The fixture helps us keep our code clean, and explicitly separate the scope of the two functions. In order to use a fixture in a test, the test has to receive the fixture name as an argument.

Therefore, we can make assertions using the test data. The tests now help us ensure that the keys from our fixtures are a subset of the list of keys we expect from the response. This makes it a lot harder for us to cheat in our tests in future, as we did before.

Running our tests again should give us a constructive error message which fails because our response does not contain all the expected keys. You can request one after registering your account on TMDb. First, we need a requests session that we will use for all HTTP interactions.

Then, we go ahead and initialize a requests session and provide the API key in the params object. This means that it will be appended as a parameter to each request we make with this session object. Next, we need to make the actual API request in the info method as follows:RESTful web services with Python is an interesting overview of the Python API frameworks space.
