ordereddict
A drop-in substitute for Py2.7's new collections.OrderedDict that works in Python 2.4-2.6.
Decision gist · record as of 2026-08-14
No. This package targets Python versions (2.4–2.6) that are no longer supported and have been obsolete for many years. Later Python versions include OrderedDict in the standard library or make all dicts ordered by default. The package is abandoned and serves no practical purpose in current development.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 2.4, 2.5, or 2.6—all versions no longer supported by Python itself or most modern tools.
- High install friction: the package has been abandoned since 2010 and targets only Python 2.4–2.6, versions long out of support.
- No active maintenance or repository presence.

What it is and what it does
OrderedDict is a backport of collections.OrderedDict to Python 2.4–2.6. It implements a dictionary that remembers the order in which keys were inserted, with performance characteristics matching regular dictionaries: O(1) amortized insertion, deletion, and lookup, and O(n) iteration, repr, copy, and equality testing.
This package is effectively obsolete. Later Python versions included OrderedDict in the standard library, and modern Python made all dicts insertion-ordered by default. The package has not been maintained since 2010 and targets only long-unsupported Python versions.
Use it for
- Maintain insertion order in dictionaries on Python 2.4–2.6 (legacy systems only).
- Backport code written for later Python OrderedDict to earlier Python 2 versions.
- Historical reference or educational study of OrderedDict implementation patterns.
