invalid syntax

This is with version 7.0.0 of the library.

Traceback (most recent call last):

Hi @aceat64 Thanks for the feedback. Currently this library requires Python 3.6 and up.

@ampledata I'd like to use your library on a "stock" Raspbian (Python 3.5.3). How big of a job do you think it is to make the library backward compatible? I can give it a shot.

Hi @castlebbs, I've added a bunch of syntactic-sugar to utilize Python 3.6's static-type-hinting: https://docs.python.org/3/library/typing.html

You could strip that stuff out since it's just additive syntax and doesn't actually change the code.

Alternatively I'd recommend using pyenv to install 3.6 into a python virtual-environment, so-as not to be constrained by whatever the Raspbian bundles: https://github.com/pyenv/pyenv

Same issue here on Xubuntu LTS which is still running python 3.5.2 by default.
