プリント私のプログラムで時間のpython 3.6

Question

を持つ学生グレード、私が変更した場合

stud1 = Student("John","Brown",["A","B","A"],["15.0","25.0","20.0"]) 

費やしたその時間を持つ学生のために選択した成績をプリントアウトするための良い方法

stud1 = Student("John","Brown",[],[]) 

いただきまし

へ。 "print（stud1.getGrade（））"の出力は（ 'A'、'15 .0 '）です。

コード：

class Student(object): 
def __init__(self, name, surname, grade, hours): 
    self.name = name 
    self.surname = surname 
    self.grade = grade 
    self.hours = hours 

def getName(self): 
    return '{}'.format(self.name) 

def getSurname(self): 
    return '{}'.format(self.surname) 

def getGrade(self): 
    #return '{} {}'.format(self.grade, self.hours) 
    for a,b in zip(self.grade, self.hours): 
     return (a,b) 

def getHours(self): 
    return '{}'.format(self.hours) 

def getQPoints(self): 
    pass 
stud1 = Student("John","Brown",["A","B","A"],["15.0","25.0","20.0"]) 
stud2 = Student("Mary","Watson","B","20") 

print (stud1.getName()) 
print (stud1.getSurname()) 
print (stud2.getName()) 
print (stud2.getSurname()) 
print (stud1.getGrade()) 
print (stud1.getHours()) 

Answer 1

def getGrade(self): 
    for a,b in zip(self.grade, self.hours): 
     return (a,b) 

def getGrade(self): 
    return zip(self.grade, self.hours)
