For simple uses for str.format(), this makes the typing easier. Hopfully this
will help in the adoption of str.format().

For example:
'The {} is {}'.format('sky', 'blue')

You can mix and matcth auto-numbering and named replacement fields:
'The {} is {color}'.format('sky', color='blue')

But you can't mix and match auto-numbering and specified numbering:
'The {0} is {}'.format('sky', 'blue')
ValueError: cannot switch from manual field specification to automatic field numbering

Issue 6089: str.format raises SystemError.
........]]> Eric Smith <eric@trueblade.com> Sat, 23 May 2009 14:04:31 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/4b4564beb6da/Objects/stringlib/string_format.h
Optimization of str.format() for cases with str, unicode, int, long,
and float arguments. This gives about 30% speed improvement for the
simplest (but most common) cases. This patch skips the __format__
dispatch, and also avoids creating an object to hold the format_spec.

Unfortunately there's a complication in 2.6 with int, long, and float
because they always expect str format_specs. So in the unicode
version of this optimization, just check for unicode objects. int,
float, long, and str can be added later, if needed.]]> Eric Smith <eric@trueblade.com> Mon, 18 Aug 2008 14:27:38 +0000 https://hg.dopieralski.pl/cpython-lru_cache-weakref/log/52294af4b663/Objects/stringlib/string_format.h
http://mail.python.org/pipermail/python-dev/2008-June/079988.html
