 `taospy` is the official Python connector for TDengine. `taospy` wraps the  [REST interface](/reference/rest-api) of TDengine. Additionally `taospy`  provides a set of programming interfaces that conforms to the [Python Data Access Specification (PEP 249)](https://peps.python.org/pep-0249/). It is easy to integrate `taospy` with many third-party tools, such as [SQLAlchemy](https://www.sqlalchemy.org/) and [pandas](https://pandas.pydata.org/).
