Solve the following python programming problem given the following code:
def _shift_like(name) : 
    def formatter(translator, expr) : 
        op = expr.op () 
        (arg, offset, default) = op.args 
        arg_formatted = translator.translate (arg) 
        if (default is not None) : 
            if (offset is None) : 
                offset_formatted = '1' 
else : 
                offset_formatted = translator.translate (offset) 
default_formatted = translator.translate (default) 
            return '{0}({1}, {2}, {3})'.format (name, arg_formatted, offset_formatted, default_formatted) 
else : 
            if (offset is not None) : 
                offset_formatted = translator.translate (offset) 
                return '{0}({1}, {2})'.format (name, arg_formatted, offset_formatted) 
else : 
                return '{0}({1})'.format (name, arg_formatted) 
return name
