  There's a way, but you don't want to use it.

  The problem you're seeing is that code runs in the scope it was *defined*
in, not the scope it is invoked in.  Functions defined in module Y and
called from module X don't see module X's globals - they see module Y's
globals.  The easiest, least painful, and cleanest way around this is to
somehow make module X's globals into parameters passed to module Y's
functions.  You can do this directly, by simply adding a parameter or two to
each function in Y, or create a class that takes each of the globals as an
__init__ argument, then keeps references to them that the now-member
functions can examine.
