Before you install
- Designed for Python 2.6, 2.7, 3.2, 3.3, and 3.4; modern Python versions have native traceback support and do not need this backport.
- Installation is straightforward with no runtime dependencies.
- However, the package is abandoned—last release was 2015-03-09 and the repository is archived.

Alternatives
Verify before relying
pip install traceback2
import traceback2 as traceback
traceback.print_exc()- Whether the unicode output behavior in Python 2.x (mentioned in the description) affects current use cases or is still relevant.
- Current compatibility with Python versions released after the package's last update in 2015.
What it is and what it does
traceback2 is a backport of Python's standard traceback module designed to provide consistent exception formatting and manipulation across older Python versions (2.6–3.4). It allows code targeting legacy Python environments to use a unified traceback API rather than dealing with version-specific differences in the standard library.
The package has no runtime dependencies and installs cleanly, but it is no longer maintained. The repository was archived and the last release occurred in 2015. Modern Python versions include the traceback functionality natively, so this package is primarily useful only for projects that must support very old Python versions that are themselves no longer receiving security updates.
Use it for
- Formatting exception tracebacks consistently in code that must run on Python 2.6 or 2.7.
- Manipulating exception frames in legacy Python 3.2–3.4 environments where the standard library traceback API differs.
- Providing unicode traceback output in Python 2.x applications that depend on linecache2.
