 `taospy` is the official Python connector for TDengine. taospy provides a rich API that makes it easy for Python applications to use TDengine. `taospy` wraps both the [native interface](/reference/connector/cpp) and [REST interface](/reference/rest-api) of TDengine, which correspond to the `taos` and `taosrest` modules of the `taospy` package, respectively.
 In addition to wrapping the native and REST interfaces, `taospy` also 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/).

 `taospy` 是 TDengine 的官方 Python 连接器。`taospy` 提供了丰富的 API， 使得 Python 应用可以很方便地使用 TDengine。`taospy` 对 TDengine 的[原生接口](../cpp)和 [REST 接口](../rest-api)都进行了封装， 分别对应 `taospy` 包的 `taos` 模块 和 `taosrest` 模块。
 除了对原生接口和 REST 接口的封装，`taospy` 还提供了符合 [Python 数据访问规范(PEP 249)](https://peps.python.org/pep-0249/) 的编程接口。这使得 `taospy` 和很多第三方工具集成变得简单，比如 [SQLAlchemy](https://www.sqlalchemy.org/) 和 [pandas](https://pandas.pydata.org/)。
