It has to be the first, because:
- you can't import members of modules directly using dot syntax
("import math.cos" will fail)
- and it can't be SimpleDialog, because Python is case-sensitive and you
wrote simpledialog.
But ignoring the import, and just looking at the dotted name:
lib.gui.simpledialog
who cares what simpledialog happens to be? So long as you know the
expected interface (say, "it's a callable object that takes three
arguments"), you can use it the same way whether it is a function, a
method, a class or something else. The implementation could change, and
you need not care.
If you actually do care what the type of simpledialog is, you can find
out easily:
type(lib.gui.simpledialog)
