# enum34 — Python 3.4 Enum backported to 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4

License: permissive · Maintenance: abandoned · Downloads: 9.3M/mo

## What it is and what it does

enum34 is a backport of Python 3.4's enum module to older Python versions (2.4–3.3). It lets you define enumerations—sets of symbolic names bound to constant values—that can be compared by identity, iterated, and looked up by name or value. The package provides the same Enum class and API as the standard library, so code written against it works identically to code using the built-in enum in modern Python.

This package was essential when Python 3.4 was new and many projects still supported Python 2.7 or early Python 3 releases. Today, it serves primarily as a dependency for legacy codebases that cannot upgrade. Since Python 2 and 3.3 are no longer supported by the Python community, and the package itself has not been maintained since 2020, installing it is rarely justified except to satisfy constraints in very old projects.

Use it for:

- Maintaining legacy Python 2.7 codebases that need enumeration support without upgrading to Python 3.
- Porting code from Python 3.4+ back to Python 3.3 or earlier when targeting older runtime environments.
- Satisfying dependency chains in archived projects that explicitly require enum34 but cannot be updated.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides enumeration support for older Python versions by backporting the standard library enum module to Python 2.4–3.3.

No, unless you are actively maintaining a legacy codebase locked to Python 2 or early Python 3. The package is abandoned, targets obsolete Python versions, and the enum module is now built into all supported Python releases. Modern projects should use the standard library enum directly.

## Install

pip install enum34
uv add enum34
poetry add enum34

## Installing enum34

Before you install: Low install friction with no runtime dependencies. However, the package is abandoned (last release 2020-03-10, over 2348 days ago) and targets Python versions that are themselves long out of support.

License in practice: BSD License (permissive) places no restrictions on use, modification, or distribution.

Quickstart:

pip install enum34

from enum import Enum

class Fruit(Enum):
    apple = 1
    banana = 2
    orange = 3

Fruit.banana
# <Fruit.banana: 2>

Targets Python 2.4–3.3; modern Python versions include enum in the standard library.

Verify before relying:

- Whether enum34 remains compatible with current Python tooling and dependency resolvers given its age and abandonment.
- Current usage patterns outside of legacy codebases that cannot upgrade.
