recursion with or without return?

P: n/a
when using recursion should one use a return statement or not?

there is a difference obv since with a return statement it will
ultimately return a value if not recursing forever.

but is there a guideline for this or it just taste or is it
considering good style or pythonic to always have a returnvalue?

This decision has nothing to do with recursion. It's the same as in
non recursive functions. If the function calculates something that you
want to return to the caller you have to use ``return``. If the function
just has side effects, e.g. printing a tree structure recursively, you
don't have to ``return`` something.

Well, you always have a return value anyway because there's an implicit
``return None`` at the end of every function.
