No it won't.

Sure, but sys.executable always exists. sys.frozen doesn't, and the
existence or nonexistence is apparently meaningful; so your code does
something different than the original problem statement.

Also, if that weren't the case, I'd really replace that try-except
with getattr(sys, 'executable', __file__)
