Question
Transcribed Image Text:It's time for the opening quidditch match of the season! We represent the various positions for players with the
QuidditchPlayer class and its subclasses. Every player begins with a base_energy level, but every position requires a
different proportion of energy. Fill in the energy method for the Beater, Chaser, Seeker, and Keeper classes, according
to their docstrings. In addition, fill in the init____ method for the Chaser class.
class Beater (QuidditchPlayer):
role="bludgers"
def energy (self, time):
******
Returns the amount of energy left after playing for time minutes.
After playing for time minutes, Beaters lose their base energy level
divided by the number of minutes. If time is 0, catch the ZeroDivisionError
and print "You can't divide by zero!" instead.
>>> fred Beater ("Fred Weasley", 640)
>>> fred.energy (40)
624.0
>>> fred.energy (0)
You can't divide by zero!

Use OK to test your code:
python3 ok -q Beater.energy
class Chaser (QuidditchPlayer):
role = "score"
energy_expended = 20
def _init__(self, name, base_energy, goals):
Chasers have a name, score goals, and begin with base_energy.
"**YOUR CODE HERE *****"
def energy (self, time):
Returns the amount of energy left after playilig for time minutes. For every goal
they score, they use energy_expended units of energy. In addition, they also use
10% of energy_expended if the number of minutes they have played is a multiple of 9.
>>> katie = Chaser("Katie Bell", 230, 2)
>>> katie.energy (20)

>>> ginny = Chaser("Ginny Weasley", 400, 3)
>>> ginny.energy (45)
