+# DataProxy-SDK-Python
+Dataproxy-SDK Python version, used for sending data to InLong dataproxy.
+
+InLong Dataproxy Python SDK is a wrapper over the existing [C++ SDK](https://github.com/apache/inlong/tree/master/inlong-sdk/dataproxy-sdk-twins/dataproxy-sdk-cpp) and exposes all of the same features.
+
+## Prerequisites
+- CMake 3.5+
+- Python 3.6+
+
+## Build
+Go to the dataproxy-sdk-python root directory, and run
+
+```bash
+chmod +x ./build.sh
+./build.sh
+```
+
+After the build process finished, you can import the package (`import inlong_dataproxy`) in your python project to use InLong dataproxy.
+
+> **Note**: When the C++ SDK or the version of Python you're using is updated, you'll need to rebuild it by re-executing the `build.sh` script
