What changed
composition/hr.pyandchoosing/hr.py:PayrollSystem.get_policy()now raisesValueError(employee_id)for an unknown employee ID instead of returning the exception instance. The tutorial's prose already says the method raises, and the update draft fixes the same line in the article's listing.The other code-family fixes in this update (the
dir()output on Python 3.13+, and the 3.12+ abstract-classTypeErrorwording) only touch REPL output in the article, so nothing else in this folder needed changing.Links
