Teaching the tools to get computers to do cool science
We just realized that in our first platypus experiment, some eggs were
poached or didn’t hatch, and we didn’t count those numbers. We want
those eggs included in total_fecundity, but we want to know how many
eggs actually hatched as well.
Create a second class, BetterPlatypus. It should be just like (inherit
from) our original Platypus class except that it takes two lists: one is
the original list of eggs laid, and the other is a list of eggs we just
found that didn’t hatch. Override the lay_eggs method so that it takes
two numbers, the number of hatched and the number of unhatched eggs.
Override total_fecundity so that it incorporates both lists.
>>> perry = BetterPlatypus("perry", [3, 2, 4, 1, 2], [0,1,0,0,1])
>>> perry.total\_fecundity()
14
>>> perry.lay_eggs(2, 1)
>>> perry.total_fecundity()
17
Fun fact: did you know that the platypus is also venomous?
