Hoisted ? With a pulley and a cable ?

The issue here is not the ability to call a function before its
declaration. It's being able to do so before its definition.

It's not either/or. Any language has to provide a way to define
functions whether or not it provides a way to declare them.

Anyway, it seems the Python way to declare a function is

  def f ():
    pass

Thanks everyone.
