Yes, if your environment is confirmed compatible with the last tested versions (flake8 3.7.9, Python 3.7.5). The plugin solves a real code-quality problem and has no security vulnerabilities. However, do not install if you require active maintenance or compatibility with very recent Python versions—test thoroughly first, since the package is abandoned and will not receive updates.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Compatibility with Python versions and tool versions beyond those tested (flake8 3.7.9, Python 3.7.5) is not guaranteed.
- High install friction: the package is abandoned (last commit 2023-01-18, no updates since 2022-03-18) and the maintainer explicitly notes they are not working on Python updates.

flake8 your_code.py- Whether the plugin remains compatible with current Python and flake8 versions beyond the tested versions (flake8 3.7.9 + Python 3.7.5).

- Current compatibility status with flake8 versions released after 2022-03-18.
What it is and what it does
flake8-blind-except is a linter plugin that enforces more specific exception handling in Python code. It flags two patterns: bare except: statements (B901) and catch-all except Exception: blocks (B902), both of which hide the true intent of error handling and can inadvertently catch system signals. The plugin integrates directly into the linting workflow once installed.
The package is unmaintained as of its latest release in 2022-03-18, with the author explicitly stating they are no longer active in Python development. While it has modest popularity, the lack of recent updates means compatibility with newer Python or linting tool versions is uncertain. The core functionality—flagging overly broad exception handlers—remains sound for codebases that can verify compatibility with their environment.
Use it for
- Enforce exception specificity in code review by catching bare except: and except Exception: patterns during linting.
- Improve code quality in legacy Python projects by identifying and refactoring catch-all exception handlers into specific exception types.
- Educate team members on exception handling best practices by making blind exception catches visible during development.
- Complement built-in linting checks by also catching broad Exception handlers beyond bare except: patterns.
