Python Application API reference

The IBM® Streams Python Application API is an open source API that is available to create stream-processing applications for IBM Streams or for the Streaming Analytics service in the cloud.

Streams are defined, processed, and sinked (terminated) by using Python functions. The return of a function determines the content of the stream. Tuples on a stream are Python objects, and a stream can contain different types of objects.
