I know, it's not as nice looking. But the advantage is that the logging system knows that regardless of what values var takes that it's the same log. This is used by Sentry to aggregate the same logs together. Also if the variable being logged also happens to contain a %s then the f-string version will throw an exception. It doesn't matter because f-strings are so fast but the % method is also lazy and doesn't interpolate/format if it's not going to be logged. Maybe in the future we'll get to use template strings for this.
Thanks for the reasons! I've been using f-strings because they're easy to keep track of, but you make really good arguments (I hadn't thought of Sentry/similar systems using %s to aggregate logs)
Well if you use loguru (and really you should, it is awesome) you would use, `logger.info("Super log {var}", var=var)` (possibly without the keys). It is also lazy and works better for structured logs.
