A backport of recent additions to the '' module.

Project description


import backports_abc

    # ABCs live in "" in Python >= 3.3
    from import Coroutine, Generator
except ImportError:
    # fall back to import from "collections" in Python <= 3.2
    from collections import Coroutine, Generator

Currently provides the following names if missing:




  • inspect.isawaitable(obj)

In Python 2.x and Python 3.2, it patches the collections module instead of the module. Any names that are already available when calling patch() will not be overwritten.

The names that were previously patched by patch() can be queried through the mapping in backports_abc.PATCHED.


0.3 (2015-07-03)

  • removed patching of inspect.iscoroutine() as it is not ABC based

0.2 (2015-07-03)

  • require explicit backports_abc.patch() call to do the patching (avoids side-effects on import and allows future configuration)

  • provide access to patched names through global PATCHED dict

  • add ABC based implementations of inspect.iscoroutine() and inspect.isawaitable()

0.1 (2015-06-24)

  • initial public release

  • provided ABCs: Generator, Coroutine, Awaitable
