Good fun! A few ideas:

How to write decorators, particularly those that take parameters.

The differences between the various number types (int, float, complex,
Fraction, Decimal) and when you'd want each one.

(CPython-specific) The dis.dis() function and what it can tell you
about how Python operates

These are all topics that have come up with my students; they're
advanced enough to be outside the scope of the course itself (the
course _uses_ decorators, but doesn't explain how to actually build
them), but not beyond the grasp of someone who's mastered Python's
fundamentals.
