flake8_deprecated

✓ flake8 registers plugins automatically; no manual import is needed.

The plugin is discovered by flake8 when installed. Incorrect to import directly.

After installing, run flake8 on your code. The plugin adds checks prefixed with 'DA' (Deprecated API).

# Sample code with deprecated calls import os os.getcwd() # Example # Run: flake8 --select=DA mycode.py

Debug

Known issues

gotchaOnly Python >=3.10 is supported as of version 2.3.0. Older Python versions will fail installation.

fix

Upgrade Python to 3.10+ or pin to an older version (e.g., flake8-deprecated==1.4) if needed.

affects: >=2.3.0

gotchaThe plugin only reports deprecated calls that are explicitly listed; it does not detect all forms of deprecation (e.g., missing deprecation warnings in third-party libs).

fix

Supplement with other tools like pylint or bandit for broader deprecated API detection.

affects: all
