Python3 Function Invoker

About

The Python 3 function invoker, as the name implies, supports functions written in Python 3. The invoker supports function arguments of type str or dict, determined by the message's Content-Type header. For messages containing Content-Type:application/json, the bytes payload is converted to a dict. Reflection is used to convert the return value. Currently only UTF-8 encoding is supported.

Supported Python Version: 3.6.x, 3.7.x

Streams (experimental)

If the function module contains a global variable interaction_model='stream', the invoker will pass a generator yielding each message payload. The response should be a generator yielding the response payload.

For example:

interaction_model = "stream"

def bidirectional(stream):
    return (item.upper() for item in stream)

Running Tests

This script will install a virtual environment for python 3.6 and run the tests.
