Code example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
| class Vehicle(object): """Docstring""" def __init__(self, color, doors, tires, vtype): """Constructor""" self.color = color self.doors = doors self.tires = tires self.vtype = vtype def brake(self): """ Stop the car """ return "%s braking" % self.vtype def drive(self): """ Drive the car """ return "I'm driving a %s %s!" % (self.color, self.vtype) if __name__ == "__main__": car = Vehicle("blue", 5 , 4, "car") print(car.brake) print(car.drive)

从中可以看出， init再次用于初始化class的参数用，或许这就是init最主要的用途，也就是对class参数的初始化。
