flake8-blind-except

library0.2.1pypypiunverified

flake8-blind-except is a `flake8` extension that identifies "blind" `except:` statements in Python code, specifically bare `except:` or `except Exception:` without logging or re-raising. It helps enforce better error handling practices by flagging these broad catches. The current version is 0.2.1, and its release cadence is slow, indicating a mature and stable plugin.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

To quickly verify `flake8-blind-except`, install both `flake8` and the plugin. Then, create a simple Python file containing a bare `except:` statement. Running `flake8` against this file will demonstrate the plugin's `B902` error detection.

# 1. Install flake8 and the plugin # pip install flake8 flake8-blind-except # 2. Create a Python file with a blind except (e.g., my_module.py) # with open('my_module.py', 'w') as f: # f.write("""try:\n 1/0\nexcept:\n pass # This will trigger B902\n""") # 3. Run flake8 on the file # This command will output the B902 error for the blind except # flake8 my_module.py

Debug

Known issues

gotchaAs a `flake8` plugin, `flake8-blind-except` relies on `flake8` itself being installed and correctly configured. Ensure `flake8` is installed in the same environment.

fix

Ensure `pip install flake8` is run in your environment alongside `flake8-blind-except`.

affects: All versions

gotchaExisting `flake8` configuration files (e.g., `pyproject.toml`, `setup.cfg`, `.flake8`) can override which checks are run. If `B902` errors are not showing up, check your `ignore` or `select` directives.

fix

Review your `flake8` configuration to ensure `B902` is not explicitly ignored and that no `select` directive is preventing its execution.

affects: All versions

gotchaThe plugin specifically targets 'blind' excepts (bare `except:` or `except Exception:`). It does not flag more specific but still overly broad catches like `except BaseException:`, which may still hide important errors.

fix

For more rigorous error handling checks, consider additional `flake8` plugins or custom rules that analyze exception types and handling logic more deeply.

affects: All versions

Errors

Common errors & fixes

flake8: command not found

The `flake8` package, which is necessary to run `flake8-blind-except`, is not installed or not available in the current shell's PATH.

fix

Install `flake8` and `flake8-blind-except` together: `pip install flake8 flake8-blind-except`.

No B902 errors reported, even with blind `except:` statements in code.

`flake8-blind-except` might not be installed, or your `flake8` configuration is explicitly ignoring `B902` or selecting a limited set of checks that exclude it.

fix

First, verify installation with `pip show flake8-blind-except`. Then, check your `flake8` configuration files (e.g., `pyproject.toml`, `setup.cfg`, `.flake8`) for `ignore = B902` or `select = ...` directives.

ModuleNotFoundError: No module named 'setuptools'

Older versions of `flake8-blind-except` (prior to 0.2.1) incorrectly listed `setuptools` in `install_requires`, which could lead to installation issues in some minimal environments.

fix

Upgrade `flake8-blind-except` to version 0.2.1 or newer: `pip install --upgrade flake8-blind-except`.
