The example got lost. But if I understand you correctly the answer is
no, not easily.
Or maybe yes, that's the default....

That's because when you call a function from inside another function the
outer
function stops executing and waits for the inner function to complete.
So when
the inner function returns you have the option of exiting the outer
function
if you want. Or you can test the return value and only exit under certain
conditions, or you can just ignore the inner function's return and continue
with the outer function. It's up to you.

But the important point is that the outer function stops while the inner
executes.
You can get round that with threading and concurrency but that's a way
more complex scenario.

If that's not what you meant you need to repost with a more complete
example.
