Modules providing forward compatibility across Python versions
Forward compatibility for Python packages, allowing future constructs to be borrowed before they’re available in the standard library.
This package is generally deprecated in favor of more surgical backports in separate packages.
Import functions from the appropriate pyXXcompat module in your python code. When you’re eventually ready to upgrade beyond pyXX, you can easily locate (with a grep) and replace those functions with the canonical implementations.
Say you want a namedtuple (introduced in Python 2.6) in a project which supports Python 2.5 and greater:
from py25compat import namedtuple MyTuple = namedtuple('MyTuple', 'a b c') mt = MyTuple(1,2,3)
With jaraco.compat installed, this code will run on Python 2.5 and greater. When the project is ready to move to Python 2.6, one can easily grep for py25compat and make the necessary replacements with minimal impact on the code. In this case:
from collections import namedtuple MyTuple = namedtuple('MyTuple', 'a b c') mt = MyTuple(1,2,3)
