Hi,

I was of the thought that Old String Formatting |"%s" % foo| was to be phased out by Advanced String Formatting |"{}.format(foo)|. I however keep seeing new code committed into the main VCS using the old style. Is this okay? Is there a policy? I ask also because I expect CPython to lead by example.

Using either is fine I think. It doesn't hurt anyone to have old string formatting around for a long time. In general, +0 for using new string formatting.

On another note, will the old format ever be deprecated? Is there a date?

I doubt it.

-- Regards, Benjamin
