Developed an enhancement for the supervisely/developer-portal repository by introducing the api.dataset.tree feature to the Python SDK, enabling retrieval of nested datasets with full path resolution in hierarchical structures. This update addressed the need for more efficient data access compared to the previous api.dataset.get_list approach. The work included comprehensive updates to Markdown-based documentation and tutorials, providing concrete examples and expected outputs to streamline developer onboarding. By focusing on both Python SDK development and clear documentation practices, the contribution improved data accessibility and usability for developers working with complex dataset hierarchies, while maintaining a guidance-driven approach to technical communication and adoption.
