python支持函数重载，和C++/Objective-c/Java类似。
适用场景:父类的方法不能满足你的需求.
代码示例如下：

class QBaseClass(object):
"""QBaseClass class"""
def __init__(self, name):
super(QBaseClass, self).__init__()
self.name = name
def showMessage(self):
print "className = %s" % (QBaseClass.__name__)
class QPerson(QBaseClass):
"""QPerson class"""
def __init__(self, name,address):
super(QPerson, self).__init__(name)
self.address = address
def showMessage(self):
print "className = %s, address = %s " % (QPerson.__name__, self.address)
p1 = QPerson("ksnowlv","北京市朝阳区")
p1.showMessage()
#下面是调用p1父类的同名方法，看起来是不是和Objective-c类似
super(QPerson,p1).showMessage()
QBaseClass.showMessage(p1)
|
运行结果如下:
ksnowlv@ksnowlvdeMacBook-Pro~/Documents/lvwei projects/python$python overloadmethod.py
className = QPerson, address = 北京市朝阳区
className = QBaseClass
className = QBaseClass
下面两种写法虽然执行结果相同，那有什么不同呢？
