Solve the following python programming problem given the following code:
def parsex(input) : 
    result = parse (input) 
    def str_if_int(x) : 
        if isinstance (x, str) : 
            return x 
return ('%d,%d' % ((x & 255), (x >> 8))) 
return '  '.join (map (str_if_int, input)) 

    
    

    Fix the buggy line: return '  '.join (map (str_if_int, input))
