I am unable to install supriya on a raspberry pi buster since it uses python3.7 and the current implantation is using such features such as the walrus operator:

In [1]: import supriya
Traceback (most recent call last):

SyntaxError: invalid syntax

Would it be possible to target 3.7 to get wider use?

Can't you use the Debian Bullseye-based Raspberry PI OS? That should support Python 3.9: https://packages.debian.org/bullseye/python3.

Thanks for your response. Unfortunately, I can't because the wifi driver I'm using for a terminal tedium is only working for the legacy version. No big deal in any case.

OK, I'll look into it. There are only a handful of walrus operator uses in the library.

I'll also have a go at making the current master 3.7 compatible.

@shakfu No need. I'm almost done. See the referenced PR #248.

@shakfu I will cut a new release soon today. Let me know if you have any additional problems installing once that goes out.
