A new SDK for A/B testing in Python has been introduced, which is open source and designed to be lightweight, fast, and free from external dependencies, allowing it to function independently. It facilitates straightforward variation assignment and user targeting, making it accessible for developers to implement A/B tests in their code. Installation is simplified through PIP, and further details, including a code example, can be found on the project's GitHub page. Additionally, users can analyze their experiment results using an open-source platform available both locally and in the cloud.
