function-sdk-python

The Python SDK for writing composition functions.

This SDK is currently a beta. We try to avoid breaking changes, but it will not have a stable API until it reaches v1.0.0. It follows the same [contributing guidelines] as Crossplane.

To learn how to use this SDK:

• Follow the guide to writing a composition function in Python
• Learn about how composition functions work
• Read the package documentation

The RunFunctionRequest and RunFunctionResponse types provided by this SDK are generated from a proto3 protocol buffer schema. Their fields behave similarly to built-in Python types like lists and dictionaries, but there are some differences. Read the generated code documentation to familiarize yourself with the the differences.

If you just want to jump in and get started, consider using the function-template-python template repository.
