If you're referring to "%s" % x versus "{}".format(x), no, there's no
official push for format. They tried that, but the push-back from people
who like the %s formatting was too large.
%s formatting is NOT deprecated, and will not be any time in the
forseeable future;
%s formatting is still necessary for anyone who wants to write code that
works with version 2.4 on up;
format() is more powerful, but also slower.
Of course individual projects and work-places may include their own
in-house rules, which may prefer %s or format. But as far as Python the
language goes, you can use whichever you prefer.
