We're thrilled to announce the preview launch of our revamped Python SDKs, bringing new capabilities and improvements to simplify your development experience. We've focused on enhancing usability, efficiency, and overall developer satisfaction. From seamless input handling, to automated validation and intuitive request building, our v2 SDKs are designed to empower developers like never before. The release introduces a new feature called `cast_models` which simplifies the process of handling user input by automatically converting values into model instances, reducing complexity for developers. We've also employed a new validation mechanism to ensure the integrity and validity of the data, integrating it seamlessly with our workflow. Once the input is cast into their expected types through `cast_models`, the next step is ensuring the integrity and validity of the data using this new validation mechanism. After retrieving the response, we invoke the `unmap` function to parse the response into a model instance, enforcing output validation to maintain consistency in data representation. The properties in your API do not always match the naming conventions in Python, so our v2 Python SDKs have a mapping functionality to solve that problem. In addition to powerful features, comprehensive descriptions and snippets are also incorporated, enhancing clarity and usability for developers. Overall, the v2 release of our Python SDKs embodies our core principles of generating human-friendly code and removing complexity from the user's hands, prioritizing clarity and ease of use.
