'%s' % x should be translated to f'{x!s}', not to f'{x:s}'. Only %s, %r and %a can be supported. Formatting with %i should left untranslated. Or maybe translate '%r: %i' % (a, x) to f'{a!r}: {"%i" % x}'.

It is possible also to introduce special opcodes that converts argument to exact int or float. Then '%06i' % x could be translated to f'{__exact_int__(x):06}'.
