Question

By Python 3 please

2. (a) Implement a class Student. For the purpose of this exercise, a student has a name and a total quiz score. Supply an appropriate constructor and methods get Name, addQuiz(score), getTotalScore(), and getAverageScore(). To compute the latter, you also need to store the number of quizzes that the student took. (b) Modify the Student class to compute grade point averages. Methods are needed to add a grade and get the current GPA. Specify grades as elements of a class Grade. Supply a constructor that constructs a grade from a string, such as "B+". You will also need a method that translates grades into their numeric values (for example, "B+" becomes 3.3). [You may obtain traditional grading scales from here http://en.wikipedia.org/wiki/Academic_grading_in_the_United_States| 3. Implement a class Car with the following properties. A car has a cer tain fuel efficiency (measured in miles/gallon) and a certain amount of fuel in the gas tank The efficiency is specified in the constructor, and the initial fuel level is 0. Supply a method drive that simulates driving the car for a certain distance, reducing the fuel level in the gas tank, and methods getGasLevel, to return the current fuel level, and addGas, to tank up. Sample usage: # 50 miles per gallon # Tank 20 gallons myHybrid = Car (50) myHybrid.addGas (20) my Hybrid.drive (100) print (myHybrid.getGasLevel ()) # Print fuel remaining #Drive 100 miles

Answer 1

Answer 3:

Code:

class Car: def _init__(self, efficiency): "Constructor to initialize efficiency and set initial fuel level to self.efficiency = efficiency self. fuellevel = 0 def addGas(self, fuel): " method to add gas to carry self. fuellevel += fuel i def drive(self, distance): "" method to simulate driving a certain distance fuelused - distance/self.efficiency self.fuellevel -= fuelused def getGasLevel(self): "" method to return the current fuel level " return self.fuellevel ___name__ == "_main_": myHybrid = Car(50) # 50 miles per gallon myHybrid.addGas (20) # Tank 20 gallons myHybrid.drive(100) # Drive 100 miles print(myHybrid.getGasLevel()) # Print fuel remaining

Code as text:

class Car:

def __init__(self, efficiency):

''' Constructor to initialize efficiency and set initial fuel level to 0 '''

self.efficiency = efficiency

self.fuellevel = 0

def addGas(self, fuel):

''' method to add gas to car '''

self.fuellevel += fuel

def drive(self, distance):

''' method to simulate driving a certain distance '''

fuelused = distance/self.efficiency

self.fuellevel -= fuelused

def getGasLevel(self):

''' method to return the current fuel level '''

return self.fuellevel

if __name__ == "__main__":

myHybrid = Car(50) # 50 miles per gallon

myHybrid.addGas(20) # Tank 20 gallons

myHybrid.drive(100) # Drive 100 miles

print(myHybrid.getGasLevel()) # Print fuel remaining
