Solve the following python programming problem given the following code:
def _is_dtype_like(self, col) : 
    '
        Check whether self.dataset.[col][0] behaves like a string, numbern
        unknown. `numpy.lib._iotools._is_string_like`
        ' 
    def string_like() : 
        try : 
            (self.dataset [col] [0] + '') 
except (TypeError, ValueError) : 
            return False 
return True 
def number_like() : 
        try : 
            (self.dataset [col] [0] + 1.0) 
except (TypeError, ValueError) : 
            return False 
return True 
if ((number_like () == True) and (string_like () == False)) : 
        return 'number' 
else : 
        if ((number_like () == False) and (string_like () == True)) : 
            return 'string' 
else : 
            assert ((number_like () == True) or (string_like () == True)), ('            Not sure of dtype' + str (string_like.dataset [col] [0])) 

    
    

    Fix the buggy line: assert ((number_like () == True) or (string_like () == True)), ('            Not sure of dtype' + str (string_like.dataset [col] [0]))
