It's definitely sad that there isn't built-in context support, but if you're looking for a solution to this, it is actually very easy to attach context to logs using threadlocal and a logging filter.

When running a webserver though, an even simpler trick is to add middleware that sets the current request's info as the current thread's name, and then including threadName in your log format.

ContextVars are seemingly more robust and work with async. We use them quite extensively for adding context to logs.

I was going to say the same, I combine ContextVars with LoggerAdapters[1].

TIL that ContextVars can work in place of thread locals too. Thanks for pointing that out!

I had mistakenly assumed ContextVars only worked for async code.

The contextual support is lacking but it can be done. See this comment from a previous discussion where I briefly described how I’ve used the record factory to help: https://news.ycombinator.com/item?id=31484527

Take a look at pylogctx maybe it'll do what you need.
