Solve the following python programming problem given the following code:
@ property 
def _getter(self) : 
    '
        Return a function object suitable for the "get" side of the property
        descriptor. This default getter returns the child element with
        matching tag name or |None| if not present.
        ' 
    def get_child_element(obj) : 
        return obj.find (qn (self._nsptagname)) 
get_child_element.__doc__ = ('``<%s>`` child element or |None| if not present.' % get_child_element._nsptagname) 
    return get_child_element 

    
    

    Fix the buggy line: get_child_element.__doc__ = ('``<%s>`` child element or |None| if not present.' % get_child_element._nsptagname)

#Here is Python program to find (qn (self.

get_child_element.__doc__ = ('``<%s>`` child element or |None| if not present.' % self._nsptagname)
