Solve the following python programming problem given the following code:
def __getattr__(self, attr) : 
    "
        Called when an attribute is not found in the usual places
        (__dict__, class tree) this method will check if the attribute
        name is a DISQUS API method and call the `call` method.
        If it isn't in the METHODS dict, it will raise an AttributeError.
        " 
    if (call_method in self.METHODS) : 
        def call_method(**kwargs) : 
            return self.call (attr, ** kwargs) 
return call_method 
raise AttributeError 

    
    

    Fix the buggy line: if (call_method in self.METHODS) :
