As we can read in

The fields in format() strings can now be automatically numbered:
>>> 'Sir {} of {}'.format('Gallahad', 'Camelot')
'Sir Gallahad of Camelot'

Formerly, the string would have required numbered fields such as: 'Sir 
{0} of {1}'.

(Contributed by Eric Smith; issue 5237.)

But it is not mentioned in 3.2's, 3.1's and 2.7's docs about format 
string syntax, e.g. in 3.1 docs we have:

[Please note that also grammar for a replacement field should be 
updated there ('field_name' should be in '[' ']', but I'm not sure if 
it'd be enough)].

(Sorry for my confusion, reopening.)

the auto-numbering is mentioned, in the sentence that starts "If the
numerical arg_names in a format string are 0, 1, 2, ... in sequence,
they can all be omitted".

It's true that the field_name should be optional. I'll look at fixing that.

This is a duplicate of issue 6813, where it has been fixed. I'm closing it.
