That is easily handled by a keyword argument. More important IMO will be the need to distinguish whether you want a format string or not. The two use cases I came up with (and posted about previously) are: print 'obj:', obj, 'refcounts', sys.getrefcount(obj) print 'obj: %s, refcounts: %s' % (obj, sys.getrefcount(obj)) Despite that these look superficially equivalent, they really aren't. The problem is that if you used one function, you'd have to make the format string selectable by keyword argument. But that's really ugly because the focus of the operation /is/ the format string, and you really want that to come first, not last, in the function call order. So the alternative is to do some magical interpretation of the first argument to decide whether it's a format string or not. Ick! So I think it's best to have two builtins: print(*args, **kws) printf(fmt, *args, **kws) I would also /require/ that any behavior changing keyword arguments /not/ be magically inferred from the positional arguments. So you'd have to explicitly spell 'nl=False' or "stream=fp" if that's what you wanted. -Barry -------------- next part -------------- A non-text attachment was scrubbed...
