Login and get codingIn 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 dict
and aBITES_DONE set
that we use (copies) in thePromo
class via its constructor (code provided).Complete the following methods in the Promo class:
_pick_random_bite
is a helper (_
here means "private", not to be called directly on an instance) that picks a randomly available Bite (use therandom
module).
When no more Bites are available raise the providedNoBitesAvailable
custom exception.new_bite
should use this helper and updateself.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).
