Hi all, I just released aiostream, a collection of generator-based operators for asynchronous iteration. - GitHub: https://github.com/vxgmichel/aiostream - PyPI: https://pypi.org/project/aiostream - Docs: http://pythonhosted.org/aiostream It can be seen as an asynchronous version of itertools, although some aspects are slightly different. The stream operators rely heavily on asynchronous generators (PEP 525), so python 3.6 is required. The project is fully tested, and the documentation provides a couple of examples: http://pythonhosted.org/aiostream/examples.html Cheers, /Vincent
