What's your actual use case (IOW, what programming problem are you trying to
solve)? Maybe there is a Python solution that will work for you, but in order
to help you find it, people here will need to better understand what you're
trying to do.

You've noticed that there isn't an identical construct for what you were doing
in Java, so it may be that the Python way will be a completely different
approach to the problem rather than just a direct conversion from Java to
Python syntax.
