    There are languages with definitions and in which
the compiler looks ahead.  FORTRAN, for example.
Python doesn't work that way.  Nor do C and the
languages derived from it, because the syntax
is context-dependent.  (In C++, "A b;" is ambiguous
until after the declaration of A. In
Pascal-derived languages, you write "var b: A;",
which is parseable before you know what A is.
So declarations don't have to be in dependency order.)

    None of this is relevant to Python, but that's
what "hoisted" means in this context..
