StringFormat

StringFormat is an independent port of the Python 3 advanced string formatting, compatible with Python >= 2.4. This implementation is pure Python.

Add the method str.format only if it is missing (Python < 2.6):

import stringformat

stringformat.init()

Enable auto-numbering fields ("{} {}" instead of "{0} {1}") with Python 2.6 also:

import sys
import stringformat

if sys.version_info < (2, 7):
    stringformat.init(True)

The advanced string formatting is officially included in the language since Python 2.6.
