Coding Guidelines
1. Pythonic Practices
- Elegance and Readability: Strive for elegant and Pythonic code that is easy to understand and maintain.
- PEP 8 Compliance: Adhere to PEP 8 guidelines for code style, with Ruff as the primary linter and formatter.
- Explicit over Implicit: Favor explicit code that clearly communicates its intent over implicit, overly concise code.
- Zen of Python: Keep the Zen of Python in mind when making design decisions.
2. Modular Design
- Single Responsibility Principle: Each module/file should have a well-defined, single responsibility.
- Reusable Components: Develop reusable functions and classes, favoring composition over inheritance.
- Package Structure: Organize code into logical packages and modules.
3. Code Quality
- Comprehensive Type Annotations: All functions, methods, and class members must have type annotations, using the most specific types possible.
- Detailed Docstrings: All functions, methods, and classes must have Google-style docstrings, thoroughly explaining their purpose, parameters, return values, and any exceptions raised. Include usage examples where helpful.
- Thorough Unit Testing: Aim for high test coverage (90% or higher) using
pytest. Test both common cases and edge cases. - Robust Exception Handling: Use specific exception types, provide informative error messages, and handle exceptions gracefully. Implement custom exception classes when needed. Avoid bare
exceptclauses. - Logging: Employ the
loggingmodule judiciously to log important events, warnings, and errors.
4. ML/AI Specific Guidelines
- Experiment Configuration: Use
hydraoryamlfor clear and reproducible experiment configurations. - Data Pipeline Management: Employ scripts or tools like
dvcto manage data preprocessing and ensure reproducibility. - Model Versioning: Utilize
git-lfsor cloud storage to track and manage model checkpoints effectively. - Experiment Logging: Maintain comprehensive logs of experiments, including parameters, results, and environmental details.
- LLM Prompt Engineering: Dedicate a module or files for managing Prompt templates with version control.
- Context Handling: Implement efficient context management for conversations, using suitable data structures like deques.
5. Performance Optimization
- Asynchronous Programming: Leverage
asyncandawaitfor I/O-bound operations to maximize concurrency. - Caching: Apply
functools.lru_cache,@cache(Python 3.9+), orfastapi.Dependscaching where appropriate. - Resource Monitoring: Use
psutilor similar to monitor resource usage and identify bottlenecks. - Memory Efficiency: Ensure proper release of unused resources to prevent memory leaks.
- Concurrency: Employ
concurrent.futuresorasyncioto manage concurrent tasks effectively. - Database Best Practices: Design database schemas efficiently, optimize queries, and use indexes wisely.
6. API Development with FastAPI
- Data Validation: Use Pydantic models for rigorous request and response data validation.
- Dependency Injection: Effectively use FastAPI's dependency injection for managing dependencies.
- Routing: Define clear and RESTful API routes using FastAPI's
APIRouter. - Background Tasks: Utilize FastAPI's
BackgroundTasksor integrate with Celery for background processing. - Security: Implement robust authentication and authorization (e.g., OAuth 2.0, JWT).
- Documentation: Auto-generate API documentation using FastAPI's OpenAPI support.
- Versioning: Plan for API versioning from the start (e.g., using URL prefixes or headers).
- CORS: Configure Cross-Origin Resource Sharing (CORS) settings correctly.
Code Example Requirements
- All functions must include type annotations.
- Must provide clear, Google-style docstrings.
- Key logic should be annotated with comments.
- Provide usage examples (e.g., in the
tests/directory or as a__main__section). - Include error handling.
- Use
rufffor code formatting.
Others
- Prioritize new features in Python 3.10+.
- When explaining code, provide clear logical explanations and code comments.
- When making suggestions, explain the rationale and potential trade-offs.
- If code examples span multiple files, clearly indicate the file name.
- Do not over-engineer solutions. Strive for simplicity and maintainability while still being efficient.
- Favor modularity, but avoid over-modularization.
- Use the most modern and efficient libraries when appropriate, but justify their use and ensure they don't add unnecessary complexity.
- When providing solutions or examples, ensure they are self-contained and executable without requiring extensive modifications.
- If a request is unclear or lacks sufficient information, ask clarifying questions before proceeding.
- Always consider the security implications of your code, especially when dealing with user inputs and external data.
- Actively use and promote best practices for the specific tasks at hand (LLM app development, data cleaning, demo creation, etc.).
