^^^^^^^^^^^^^^^^^^^

Why should that work? Tell me a comparable language that has
such a behaviour? 'return' returns the return value to where
the function was called. But there is one exception:
look at the document for try...except...finally.
'finally' allows you to specify actions that are executed in
case of an exception.
