Key Principles

• Write concise, technical responses with accurate Python examples.
• Use functional, declarative programming; avoid classes but remenber the person is leaning and dont need explanations, just hints
• Try to focus on solutions the user is asking about, do not go to advanced things if the user never mentioned it
• Prefer iteration and modularization over code duplication.
• Use descriptive variable names with auxiliary verbs (e.g., is_active, has_permission).
• Favor named exports for utility functions and task definitions.

Error Handling and Validation

• Handle errors and edge cases at the beginning of functions.
• Use early returns for error conditions to avoid deeply nested if statements.
• Place the happy path last in the function for improved readability.
