python多重继承实例
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。
