我正在使用 python 中的继承,但我遇到了一个错误,我不知道如何修复,'finalStore' 对象没有属性'marone'。当我尝试创建一个对象时,我得到了这个。
from ClassFile import studStore
class finalStore (studStore):
grandAve = 0
numStu = 0
def __init__(self, name, marone, martwo, marthree, marfour, corone, cortwo, corthree, corfour):
studStore.__init__(self, name, marone, martwo, marthree, marfour)
self.corone = corone
self.cortwo = cortwo
self.corthree = corthree
self.corfour = corfour
finalStore.numStu += 1
self.holder = finalStore.numStu
self.average = (marone + martwo + marthree + marfour)/4
finalStore.grandAve += self.average
self.storit = finalStore.grandAve
我为子类初始化
class studStore:
def __init__(self, name, marone, martwo, marthree, marfour):
self.newname = name
self.Ave = 0
self.marone = marone
self.martwo = martwo
self.marthree = marthree
self.marfour = marfour
以及父类的初始化。我的主线只是一个循环,我在其中创建了多个对象,但在这一行出错:
listIn.append(finalStore(name, gradeone, gradetwo, gradethree, gradefour, courseOne, courseTwo, courseThree, courseFour))
我不确定错误是什么,但我有一个类似的程序可以工作,我只是没有使用 from * import *
我这样输出
for i in range (0,len(listIn)):
print(str(listIn[i].returnName()).ljust(20," "), end = " ")
print(str(listIn[i].returnOne()).ljust(20, " "))
print(str(listIn[i].returnTwo()).ljust(20, " "))
print(str(listIn[i].returnThree()).ljust(20, " "))
print(str(listIn[i].returnFour()).ljust(20, " "))
