In this bite a real world scenario: PyBites has a growing set of Bites and gives away promos. They choose a Bite randomly but don't want to choose the same one again.
Hence you are provided with a
BITES dictand a
BITES_DONE setthat we use (copies) in the
Promoclass via its constructor (code provided).
Complete the following methods in the Promo class:
_pick_random_biteis a helper (
_here means "private", not to be called directly on an instance) that picks a randomly available Bite (use the
When no more Bites are available raise the provided
new_biteshould use this helper and update
self.bites_done(it keeps state, the reason we used a class here).
See also the tests. We hope you learn a thing or two. Enjoy!
Update 4th of Nov 2020: we changed this Bite slightly to localize the Bite constants (thanks Kenneth). No worries: it's all done in the
__init__constructor for you, you don't have to change anything there).
