我想使用doctest注释块来演示特定基类的用法,但要么这不能用doctest完成,要么我做错了.这是我的简单演示代码.

class MyClass(object):
    '''
    >>> m = MyClass()
    >>> print m.x
    1
    >>> class A(MyClass):
    >>>  def __init__(self):
    >>>    super(A,self).__init__()
    >>>
    >>> a = A()
    >>> print a.x
    1
    '''


    def __init__(self):
        self.x = 1


if __name__ == "__main__":
    import doctest
    doctest.testmod()    

代码无法运行.这是发出的第一个错误:

Failed example:
class A(MyClass):
Exception raised:
