Logged In: YES user_id=38388 Why would we need a method for formatting ? We already have the %-based formatting which can also be access via .__mod__().

Logged In: YES user_id=6380 I like this. The reason to like this in favor of s%x was expressed by Walter Dörwald on the python-3000 list: """ it avoids one problem you might run into with %: If you have only one argument, writing ``s % (x,)`` as ``s % x`` will break when the argument x happens to be a tuple. You won't have this problem with s.format(x). """ However, this might be our chance to introduce a new formatting syntax, since there are many problems with the %s style (especially %(foo)s). See PEP 292. We need a Python 3000 group in the trackers.

Logged In: YES user_id=38388 I would rather like to see any non-trivial formatting be moved into a module and have functions that operate on strings and Unicode. Methods on simple types shouldn't really implement any complicated features. Formatting is one of those things that everybody wants to implement in different ways. Just look at the gazillion different templating engines out there for examples :-) Better remove the %-formatting altogether in Py3k and add a module which implements 2.x style %-formatting as well as pep 292 style $-formatting.
