The usual idiom is to construct a list of pieces and then join with ''. >>> print(''.join(['1', '2'])) 12 Or map str to a list of objects. >>> print(''.join(map(str, [1, 2]))) 12 You can do either of these in 2.x. If you use .write, include '\n' at the end of the list (when needed). Print was designed as a quick and easy way to put lines of text on the screen. Then people asked for a way to use with with other streams, hence the >> hack. Then people wanted ways to control the separator and terminator. As that point, Guido realized that it needed to be a function, not a statement, with all the options requested. -- Terry Jan Reedy
