library1.1pypypiunverified

The 'ordereddict' library provides a backport of the `collections.OrderedDict` class, originally introduced in Python 2.7 and 3.1, for use in older Python 2.x environments (specifically Python 2.4, 2.5, and 2.6). It enables maintaining the insertion order of keys in a dictionary-like structure. This package is no longer maintained and serves only historical compatibility purposes for very old Python 2 projects.

OrderedDict

✓ from ordereddict import OrderedDict

✗ import ordereddict

Demonstrates importing and using the `OrderedDict` class from the backport for Python 2.4-2.6. It includes a version check to highlight the library's specific compatibility window.

import sys # This library is for Python 2.x <= 2.6 # For Python 2.7+ or 3.x, use 'from collections import OrderedDict' if sys.version_info < (2, 7) and sys.version_info >= (2, 4): from ordereddict import OrderedDict print("Using ordereddict backport") od = OrderedDict() od['first'] = 1 od['second'] = 2 od['third'] = 3 print(od.items()) else: print("This library is not needed for your Python version.") print("Use 'from collections import OrderedDict' instead.")

Debug

Known issues

breakingThis 'ordereddict' library is obsolete for modern Python versions. `collections.OrderedDict` is built into Python 2.7, Python 3.1, and later. Furthermore, standard Python dictionaries (`dict`) guarantee insertion order since Python 3.7.

fix

For Python 2.7+, use `from collections import OrderedDict`. For Python 3.7+, a regular `dict` maintains insertion order, so `OrderedDict` might only be needed for specific API compatibility or advanced features like `move_to_end` or order-sensitive equality comparisons.

affects: Python 2.7+, Python 3.x

gotchaThe performance characteristics of this Python-based backport `ordereddict.OrderedDict` may differ significantly from the C-optimized `collections.OrderedDict` in newer Python versions.

fix

Avoid using this backport unless strictly required for compatibility with Python 2.4-2.6. Prioritize `collections.OrderedDict` or standard `dict` where possible.

affects: All versions
