enum34
Python 3.4 Enum backported to 3.3, 3.2, 3.1, 2.7, 2.6, 2.5, and 2.4
Decision gist · record as of 2026-08-14
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.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Targets Python 2.4–3.3; modern Python versions include enum in the standard library.
- 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.

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.
