python实现的工厂方法--设计模式初级

class Driver:
def __init__(self,carType='default',driver='Tom'):
self.carType=carType
self.driver=driver
def toString(self):
return ' '.join([self.driver,'drive',self.carType])

def creatCarFactory(carType):
def setCarDriver(carDriver):
return Driver(carType,carDriver)
return setCarDriver
if __name__=="__main__":
bus = creatCarFactory('bus')
xalDriveBus = bus('xal')
timDriveBus = bus('Tim')
car = creatCarFactory('car')
xalDriveCar = car('xal')
print(xalDriveBus.toString())
