Well, that second example certainly is a WTF.
I think we are supposed to prefer:
'{0}{0}'.format('wtf?')
to
'%%s%s' % 'wtf?' % 'wtf?'
But your replacement misses the point of the example,
which is that sequential formatting is often needed.
That is, you need to generate a format string from
a format string. More explicitly:
'{{0}} {0}'.format('earlyinfo').format('lateinfo')
'%%s %s' % 'earlyinfo' % 'lateinfo'
But of more interest: you claim PEP 4 is not relevant,
and that old string formatting is NOT deprecated.
I would like assurance that it is not deprecated.
Can you back that?
Thanks,
