pythonオブジェクト向けフォーマットが重要

class Vehicle:

    def __int__(self,speed):

        self.speed=speed



        def drive(self,distance):

            print 'need %f hour(s)'%(distance/self.speed)



class Bike(Vehicle):

    pass

class Car(Vehicle):

    def __init__(self,speed,fuel):

        Vehicle.__int__(self,speed)

        self.fuel=fuel



    def drive(self,distance):

        Vehicle.drive(self,distance)

        print 'need %f fules'%(distance*self.fuel)





        b=Bike(15.0)

        c=Car(80.0,0.012)

        b.drive(100.0)

        c.drive(100.0)

　　

class Vehicle:

        def __init__(self,sudu):

            self.sudu =sudu



        def drive(self,distance):

            print 'need %f hour(s)'%(distance/self.sudu)



class Bike(Vehicle):

    pass

class Car(Vehicle):

    def __init__(self, speed, fuel):

        Vehicle.__init__(self, speed)

        self.fuel = fuel



    def drive(self, distance):

        Vehicle.drive(self, distance)

        print 'need %f fuels' % (distance * self.fuel)

b=Bike(10.0)

b.drive(100.0)

c=Car(80.0,0.012)

c.drive(100.0)

フォーマットの問題ではありません上のコードinitはintを書いてコードを書くのはきっと注意しなければなりません
