python的方法存贮在类中还是对象中？

Question

请问各位大侠，类中的方法在内存中的存储是在类中还是对象中？

Answer 1

 In [263]: class Sample(object):
     ...:     def ordinary(self):
     ...:         print "I'm a ordinary method"
     ...:     @classmethod
     ...:     def clsmethod(cls):
     ...:         print "I'm a class method"
     ...:     @staticmethod
     ...:     def stcmethod():
     ...:         print "I'm a static method"
     ...:         

In [264]: a = Sample()

In [265]: b = Sample()

In [266]: a.ordinary == Sample.ordinary # 普通方法，各自存储
Out[266]: False

In [267]: a.ordinary == b.ordinary
Out[267]: False

In [268]: a.clsmethod == Sample.clsmethod # 类方法存储在类中
Out[268]: True

In [269]: a.stcmethod == Sample.stcmethod # 静态方法存储在类中
Out[269]: True

In [270]: a.ordinary.im\_func == Sample.ordinary.im\_func
Out[270]: True
