Python Best Practices

Code Style

• Follow PEP 8 style guide
• Use snake_case for functions/variables
• Use PascalCase for classes
• Maximum line length: 88 (Black) or 79 (PEP 8)
• Use meaningful variable names

Modern Python (3.10+)

• Use f-strings for formatting: f"Hello {name}"
• Use pathlib for file paths instead of os.path
• Use dataclasses or Pydantic for data models
• Type hints for function signatures
• Use walrus operator := for assignment expressions
• Use match-case for pattern matching
• Use | for union types instead of Union
