Solve the following python programming problem given the following code:
def __call__(self, func) : 
    'Decorator which returns the elapsed time of the function call.' 
    if (not self.metric) : 
        self.metric = ('%s.%s' % (func.__module__, self.__name__)) 
@ wraps (func) 
    def wrapped(* args, **kwargs) : 
        start = time () 
        try : 
            return func (* args, ** kwargs) 
finally : 
            self._send (start) 
return wrapped 

    
    

    Fix the buggy line: self.metric = ('%s.%s' % (func.__module__, self.__name__))

#Here is Python code to fix the buggy line: self.

self.metric = ('%s.%s' % (func.__module__, func.__name__))
