Anyone have a clever solution for optionally using new python features while still supporting lower python 3 versions? For packaging purposes. Could put try except blocks everywhere or selectively import 3.10 modules vs <=3.9 modules, for example. I find that new features aren’t necessary for their functionality, but they often can make code more terse, so having “duplicate” code with the same functionality but without new terseness kind of defeats the purpose. I suppose having two versions of the same module lets you end support for an old version pretty simply, but is that useful?
