{"id":1798,"library":"alibabacloud-tea-openapi","title":"Alibaba Cloud Tea OpenAPI","description":"Alibaba Cloud Tea OpenAPI is a core Python SDK library that provides the fundamental structures and utilities for interacting with Alibaba Cloud's OpenAPI services. It primarily defines the `Config` object for client configuration, enabling developers to set credentials, endpoints, and other essential parameters for making API requests.
