Python 子类调用父类的构造函数

BaseClassName.methodname(self, arguments)

>>> class A:
...     def hello(self):
...         print 'a'
...
>>> A().hello()
a
>>> class C(A):
...     def hello(self):
...         A.hello(self)
...         print 'c'
...
>>> C().hello()
a
c

For new-style class (any class which inherits from [code]object

super(ClassName, self).method(args)

>>> class M(object):
...     def hello(self):
...         print 'm'
...
>>> class N(M):
...     def hello(self):
...         super(N, self).hello()
...         print 'n'
...
>>> N().hello()
m
n
