本文实例讲述了python多重继承用法,分享给大家供大家参考。具体实现方法如下:
1.mro.py文件如下:
#!/usr/bin/python
# Filename:mro.py
class P1:
def foo(self):
print 'called P1-foo'
class P2:
def foo(self):
print 'called P2-foo'
def bar(self):
print 'called P2-bar'
class C1(P1, P2):
pass
class C2(P1, P2):
def bar(self):
print 'called C2-bar()'
class GC(C1, C2):
pass
2.执行结果如下:
> from mro import * > gc = GC() > gc.foo() called P1-foo > gc.bar <bound method GC.bar of <mro.GC instance at 0xb77be2ac > gc.bar() called P2-bar >
3.结论:
方法解释顺序(MRO): 深度优先, 从左至右
希望本文所述对大家的Python程序设计有所帮助。
