Re: [weewx-development] Format of weewx-variables/datafields for arithmetic (service development)?

I guess this is as good a time as any to ask if None is the way Weewx represents a nonexistent element of data for the result of a query to any of its API functions. For example, if I want the barometric pressure at 9am, and no pressure was recorded around that time, is it None that would be

That’s why one option I was suggesting was to just print out the location of the log vs its contents. The idea is to avoid requiring the user to figure out where their log is located, and just either have a tool tell them, or just grab the current log from wherever it was stored and dump it out.

If there’s a new format, I’d much prefer TOML vs. JSON/YAML. TOML makes some improvements over ini files, without being an easy-for-humans-to-make-mistakes format like JSON.But it sounds like the issue is more fundamental- that the issue has something to do with the new Python package installer

My system still has Python2 installed. I also have Python-3.8.1. Here's what I had to do to get weewx 4.0.0b12 working on my system, which supports both python2 and python3 simultaneously: 1. Since "python" on my system resolves to Python2 - I had to change the executable scripts in
