Project B — Coding Standards

Stack

• Python 3
• unittest for testing

Conventions

• Follow PEP 8 style
• Use type hints where practical
• Keep functions small and focused
• Use docstrings for public functions

Testing

• All new functionality must have tests
• Run tests with python -m pytest or python -m unittest discover
• Test file naming: test_*.py

PR Conventions

• Branch naming: fix/issue-N-description, feat/issue-N-description
• Commit style: Fix #N: description or Feat #N: description

Things You Must Never Do

• Never commit secrets or API keys
• Never use eval() or exec() on user input
• Never ignore exceptions silently (no bare except: pass)
• Never push directly to main — always use PRs
