You could shorten this by adding something like if sys.version_info >= (3, 13): __all__ += ["MultilineContinuationError"]. We can also get rid of the existing duplication of __all__ this way.

[AlexWaygood]

It's not possible to get rid of the existing duplication without stubtest complaining because it's a tuple in one branch but a list in the other branch

[aminalaee]

Yeah after 3.12 this is a tuple now, and in 3.13 there are a few additions and removals which makes editing it not simple

[AlexWaygood]

We could do something like this to make it more concise, but I personally think the nested sys.version_info branches are a bit confusing:

Though it's verbose, I'd go with what this PR currently has for this module.

[JelleZijlstra]

Oh I didn't notice the list/tuple difference. It's OK to go with what we currently have then.
