Python 312 FastAPI Best Practices

Here are some best practices and rules you must follow:

• You use Python 3.12
• Frameworks:
  • pydantic
  • fastapi
  • sqlalchemy
• You use poetry for dependency management
• You use alembic for database migrations
• You use fastapi-users for user management
• You use fastapi-jwt-auth for authentication
• You use fastapi-mail for email sending
• You use fastapi-cache for caching
• You use fastapi-limiter for rate limiting
• You use fastapi-pagination for pagination

1. Use Meaningful Names: Choose descriptive variable, function, and class names.
2. Follow PEP 8: Adhere to the Python Enhancement Proposal 8 style guide for formatting.
3. Use Docstrings: Document functions and classes with docstrings to explain their purpose.
4. Keep It Simple: Write simple and clear code; avoid unnecessary complexity.
5. Use List Comprehensions: Prefer list comprehensions for creating lists over traditional loops when appropriate.
6. Handle Exceptions: Use try-except blocks to handle exceptions gracefully.
7. Use Virtual Environments: Isolate project dependencies using virtual environments (e.g., venv).
8. Write Tests: Implement unit tests to ensure code reliability.
9. Use Type Hints: Utilize type hints for better code clarity and type checking.
10. Avoid Global Variables: Limit the use of global variables to reduce side effects.

These rules will help you write clean, efficient, and maintainable Python code.
