Overview: what does it do?

The Learnosity Python SDK makes it simple to interact with Learnosity APIs.


It provides a number of convenience features for developers, that make it simple to do the following essential tasks:

  • Creating signed security requests for API initialization, and
  • Interacting with the Data API.

For example, the SDK helps with creating a signed request for Learnosity:


Once the SDK has created the signed request for you, your app sends that on to an API in the Learnosity cloud, which then retrieves the assessment you are asking for, as seen in the diagram below:


This scenario is what you can see running in the Quick start guide example (see below).

There's more features, besides. See the detailed list of SDK features on the reference page.

  1. Runtime libraries for Python 3 installed. (instructions)

  2. The Pip package manager installed. You use Pip to access the Learnosity Python SDK on Pypi (the Python Package Index).

  3. The Jinja** templating library. For the tutorial on this page, you will also need Jinja installed. Jinja helps in rendering HTML templates, and importing Python variables into web pages. It's not actually a requirement of the SDK itself, so if your app doesn't use Jinja, no need to install it. ** Jinja is only required for the tutorial on this page.

Not using Python? See the SDKs for other languages.

Supported Python Versions

We support all versions that have a status of bugfix or security on this list.

Installation via Pip

Using Pip is the recommended way to install the Learnosity SDK for Python in production. The easiest way is to run this from your parent project folder:

pip install learnosity_sdk

Then, if you're following the tutorial on this page, also run:

pip install learnosity_sdk[quickstart]

Alternative method 1: download the zip file

Download the latest version of the SDK as a self-contained ZIP file from the GitHub Releases page. The distribution ZIP file contains all the necessary dependencies.

Note: after installation, run this command in the SDK root folder:

pip install .

Alternative 2: development install from a git clone

To install from the terminal, run the following command:

git clone

To set up up your local development environment, use the following:

python3 -m venv .venv/learnosity-sdk-python
source .venv/learnosity-sdk-python/bin/activate
pip install -e .

Note that these manual installation methods are for development and testing only. For production use, you should install the SDK using the Pip package manager for Python, as described above.

Quick start guide

Let's take a look at a simple example of the SDK in action. In this example, we'll load an assessment into the browser.

Start up your web server and view the standalone assessment example

To start up your Python web server, run the following command:


Note: this will run the code in

From this point on, we'll assume that your web server is available at this local address (it will report the port being used when you launch it, by default it's port 8000).


You can now access the APIs using the following URL click here.

Following are the routes to access our APIs.

Open these pages with your web browser. These are all basic examples of Learnosity's integration. You can interact with these demo pages to try out the various APIs. The Items API example is a basic example of an assessment loaded into a web page with Learnosity's assessment player. You can interact with this demo assessment to try out the various Question types.

How it works

Let's walk through the code for this standalone assessment example. The source file is included under the quickstart folder:

The first section of code is Python and is executed server-side. It constructs a set of configuration options for Items API, and securely signs them using the consumer key. The second section is HTML and JavaScript and is executed client-side, once the page is loaded in the browser. It renders and runs the assessment functionality.

(Back to top)

Server-side code

We start by including some LearnositySDK helpers - they'll make it easy to generate and sign the config options, and generate unique user and session IDs.

from learnosity_sdk.request import Init # Learnosity helper.
from learnosity_sdk.utils import Uuid   # Learnosity helper.
from .. import config          #, which stores the consumer key and secret.

We also specify a few libraries to run a minimal web server, for the purposes of this example.

from http.server import BaseHTTPRequestHandler, HTTPServer # Python web server.
from jinja2 import Template             # Jinja template library - pulls data into web pages.

We generate UUIDs for the user ID and session ID.

user_id = Uuid.generate()
session_id = Uuid.generate()

We choose the host domain and port number for our local web server.

host = "localhost"
port = 8000

Now we'll declare the configuration parameters for Items API. These specify which assessment content should be rendered, how it should be displayed, which user is taking this assessment and how their responses should be stored.

items_request = items_request = {
    "user_id": user_id,
    "activity_template_id": "quickstart_examples_activity_template_001",
    "session_id": session_id,
    "activity_id": "quickstart_examples_activity_001",
    "rendering_type": "assess",
    "type": "submit_practice",
    "name": "Items API Quickstart",
    "state": "initial"
  • user_id: unique student identifier. Note: we never send or save student's names or other personally identifiable information in these requests. The unique identifier should be used to look up the entry in a database of students accessible within your system only. Learn more.
  • activity_template_id: reference of the Activity to retrieve from the Item bank. The Activity defines which Items will be served in this assessment.
  • session_id: uniquely identifies this specific assessment attempt for save/resume, data retrieval and reporting purposes. Here, we're using the Uuid helper to auto-generate a unique session id.
  • activity_id: a string you define, used solely for analytics to allow you run reporting and compare results of users submitting the same assessment.
  • rendering_type: selects a rendering mode, assess mode is a "standalone" mode (loading a complete assessment player for navigation, as opposed to inline for embedding without).
  • type: selects the context for the student response storage. submit_practice mode means the student responses will be stored in the Learnosity cloud, allowing for grading and review.
  • name: human-friendly display name to be shown in reporting, via Reports API and Data API.
  • state: Optional. Can be set to initial, resume or review. initial is the default.

Note: you can submit the configuration options either as a Python array as shown above, or a JSON string.

Next, we declare the Learnosity consumer credentials we'll use to authorize this request. We also construct security settings that ensure the report is initialized on the intended domain. The value provided to the domain property must match the domain from which the file is actually served. The consumer key and consumer secret in this example are for Learnosity's public "demos" account. Once Learnosity provides your own consumer credentials, your Item bank and assessment data will be tied to your own consumer key and secret.

security = {
    'consumer_key': config.consumer_key,
    'domain': host,

(of course, you should never normally put passwords into version control)

Now we call LearnositySDK's Init() helper to construct our Items API configuration parameters, and sign them securely with the security, request and config.consumer_secret parameters. init.generate() returns us a JSON blob of signed configuration parameters.

init = Init(
    'items', security, config.consumer_secret,
generated_request = init.generate()

Web page content

We've got our set of signed configuration parameters, so now we can set up our page content for output. The page can be as simple or as complex as needed, using your own HTML, JavaScript and your frameworks of choice to render the desired product experience.

This example uses plain HTML in a Jinja template, served by the built-in Python web server. However, the Jinja template used here can be easily re-used in another framework, for example Python Flask or Django.

The following example HTML/Jinja template can be found near the bottom of the file.

        template = Template("""<!DOCTYPE html>
                <link rel="stylesheet" type="text/css" href="../css/style.css">
                <h1>{{ name }}</title></h1>
                <!-- Items API will render the assessment app into this div. -->
                <div id="learnosity_assess"></div>
                <!-- Load the Items API library. -->
                <script src=\"\"></script>
                <!-- Initiate Items API assessment rendering, using the signed parameters. -->
                    var itemsApp = LearnosityItems.init( {{ generated_request }} );

The important parts to be aware of in this HTML are:

  • A div with id="learnosity_assess". This is where the Learnosity assessment player will be rendered to deliver the assessment.
  • The <script src=""></script> tag, which includes Learnosity's Items API on the page and makes the global LearnosityItems object available. The version specified as latest-lts will retrieve the latest version supported. To know more about switching to specific LTS version visit Long Term Support (LTS) version. In production, you should always pin to a specific LTS version to ensure version compatibility.
  • The call to LearnosityItems.init(), which initiates Items API to inject the assessment player into the page.
  • The variable {{generated_request}} dynamically sends the contents of our init options to JavaScript, so it can be passed to init().

The call to init() returns an instance of the ItemsApp, which we can use to programmatically drive the assessment using its methods. We pull in our Learnosity configuration in a variable {{ generated_request }}, that the Jinja template will import from the Python program. The variable {{ name }} is the page title which can be set in the same way.

The Jinja template is rendered by the following line, which will bring in those variables.

    response = template.render(name='Standalone Assessment Example', generated_request=generated_request) 

There is some additional code in, which runs Python's built-in web server.

This marks the end of the quick start guide. From here, try modifying the example files yourself, you are welcome to use this code as a basis for your own projects. As mentioned earlier, the Jinja template used here can be easily re-used in another framework, for example Python Flask or Django.
