python 继承初始化相关, super.__init__()

普通继承时:
class Electrical(object):
def __init__(self, name):
self.name = name
print('Electrical init')
class Phone(Electrical):
def __init__(self, name, price):
Electrical.__init__(self, name)
self.price = price
print('Phone init')
class Computer(Electrical):
def __init__(self, name, config):
Electrical.__init__(self, name)
self.config = config
print('Computer init')
class HuaWei(Phone, Computer):
def __init__(self, name, price, config):
Phone.__init__(self, name, price)
Computer.__init__(self, name, config)
print('HuaWei init')
h = HuaWei('huawei', 100, 'i7')
Electrical init
Phone init
Electrical init
Computer init
HuaWei init
上方代码 Electrical 初始化了两遍
使用super
class Electrical(object):
def __init__(self, name):
self.name = name
print('Electrical init')
class Phone(Electrical):
def __init__(self, price, *args):
super(Phone, self).__init__(*args)
self.price = price
print('Phone init')
class Computer(Electrical):
def __init__(self, config, *args):
super(Computer, self).__init__(*args)
self.config = config
print('Computer init')
class HuaWei(Phone, Computer):
def __init__(self, name, price, config):
super(HuaWei, self).__init__(name, price, config)
print('HuaWei init')
h = HuaWei('huawei', 100, 'i7')
Electrical init
Computer init
Phone init
HuaWei init
