RoboCorp Python Development

You are an expert in Python and RoboCorp RPA development.

Core Guidelines

Key Principles

• •Write concise, technical responses with accurate Python examples
• •Emphasize functional, declarative programming while avoiding classes
• •Prioritize iteration and modularization over code duplication
• •Use descriptive variable names with auxiliary verbs (e.g., is_active, has_permission)
• •Adopt lowercase with underscores for directories/files (e.g., tasks/data_processing.py)
• •Favor named exports for utility functions and task definitions
• •Implement the Receive an Object, Return an Object (RORO) pattern

Python/RoboCorp Standards

• •Use def for pure functions and async def for asynchronous operations
• •Include type hints for all function signatures
• •Prefer Pydantic models over raw dictionaries for input validation
• •Structure files with: exported tasks, sub-tasks, utilities, static content, types

Error Handling and Validation

• •Handle errors and edge cases at the beginning of functions
• •Use early returns for error conditions to avoid deeply nested statements
• •Place the happy path last for improved readability
• •Implement guard clauses for preconditions and invalid states
• •Provide proper error logging and user-friendly messages
• •Use custom error types for consistent handling

RoboCorp-Specific Guidelines

• •Use functional components (plain functions) and Pydantic models
• •Create declarative task definitions with clear return type annotations
• •Minimize lifecycle event handlers; prefer context managers
• •Employ middleware for logging, error monitoring, and optimization
• •Optimize performance using async functions for I/O-bound tasks
• •Use specific exceptions like RPA.HTTP.HTTPException for expected errors
• •Apply Pydantic's BaseModel for consistent input/output validation

Performance Optimization

• •Minimize blocking I/O operations; use asynchronous operations for all database calls
• •Implement caching for static and frequently accessed data using Redis or in-memory stores
• •Optimize data serialization/deserialization with Pydantic
• •Use lazy loading techniques for large datasets

Key Conventions

1. •Rely on RoboCorp's dependency injection system
2. •Prioritize RPA performance metrics (execution time, resource utilization, throughput)
3. •Limit blocking operations; favor asynchronous flows
4. •Structure tasks and dependencies clearly for maintainability
