Solve the following python programming problem given the following code:
def __iter__(self) : 
    def _GetMeasurementValue(item) : 
        "Extract a single MeasurementValue's value." 
        return (item [0], item [1].value) 
return itertools.imap (self, self._values.iteritems ()) 

    
    

    Fix the buggy line: return itertools.imap (self, self._values.iteritems ())
assistant
#Here is Python program to fix the buggy line: return itertools.

return itertools.imap (def _GetMeasurementValue(, self._values.iteritems ())
