python super用法
普通继承
class FooParent(object):
def __init__(self):
self.parent = 'I\'m the parent.'
print 'Parent'
def bar(self, message):
print message, 'from Parent'
class FooChild(FooParent):
def __init__(self):
FooParent.__init__(self)
print 'Child'
def bar(self, message):
FooParent.bar(self, message)
print 'Child bar function.'
print self.parent
if __name__ == '__main__':
foochild = FooChild()
foochild.bar('Hello World!')
# output
Parent
Child
Hello World! from Parent
Child bar function.
I'm the parent.
