Sharing package data across files

I have a standalone script that grew and grew until reaching an unmaintainable size.  I was hoping to refactor it into a relatively small top-level script plus a package containing a bunch of relatively small files.

Easier, yes.  Correct, no:

    from vars import foo

    def bar():
        global foo
        foo += 1
        return foo

which surprisingly (to me, anyway) changes a _copy_ of foo, not the foo I'd think of as belonging to the example package:

    >>> from example import foo, bar
    >>> foo
    123
    >>> bar()
    124
    >>> foo
    123

That kind of defeats my goal of splitting a single file into more maintainable chunks.
