The print statement harks back to ABC and even (unvisual) Basic. Out with it! A transitional strategy could be to start designing the new API and introduce it in Python 2.x. Here's my strawman: (1) Add two new methods the the stream (file) API and extend write(): stream.write(a1, a2, ...) -- equivalent to map(stream.write, map(str, [a1, a2, ...])) stream.writeln(a1, a2, ...) -- equivalent to stream.write(a1, a2, ..., "\n") stream.writef(fmt, a1, a2, ...) -- equivalent to stream.write(fmt % (a1, a2, ...)) (2) Add builtin functions write(), writeln(), writef() that call the corresponding method on sys.stdout. (Note: these should not just be the bound methods; assignment to sys.stdout should immediately affect those, just like for print. There's an important use case for this.) -- --Guido van Rossum (home page: http://www.python.org/~guido/) _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
