为么跟书上说的不一样呢？
>>> class FooClass(object):
... version=0.1
... def _init_(self,nn='John Doe'):
... self.name=nm
... print 'Created aclass instance for',nm
... def showname(self):
... print 'Your name is',self.name
... print 'My name is',self._clsss_.name
... def showver(self):
... print self.version
... def addMe2Me(self,x):
... return x+x
...
>>> fool=FooClass()
>>>
书上说会显示 Created class instance for John Doe

[解决办法]
_init_改__init__2个下划线，python要求缩进正确，上代码时贴到[code=Python][/code]标签之间，不然会乱掉...

构造方法都写错了，还有注意缩进
