What this skill does
Python Style Guide Comprehensive guidelines for writing clean, maintainable Python code based on Google's Python Style Guide. Core Philosophy BE CONSISTENT. Match the style of the code around you. Use these guidelines as defaults, but always prioritize consistency with existing code. Language Rules Imports Use import statements for packages and modules only, not for individual classes or functions. Yes: No: Import Formatting Group imports: standard library, third-party, application-specific Alphabetize within each group Use absolute imports (not relative imports) One import per line (except for multiple items from typing or collections.abc) Exceptions Use exceptions appropriately. Do not suppress errors with bare except: clauses. Yes: No: Type Annotations Annotate all function signatures. Type annotations improve code readability and catch errors early. General rules: Annotate all public APIs Use built-in types (list, dict, set) instead of typing.List, etc. (Python 3.9+) Import typing symbols directly: from typing import Any, Union Use None instead of type(None) or NoneType Default Argument Values Never use mutable objects as default values in function definitions. Yes: No: True/False Evaluations Use implicit false where possible. Empty sequences, None, and 0 are false in boolean contexts. Yes: No: Comprehensions & Generators Use comprehensions and generators for simple cases. Keep them readable. Yes: No: Lambda Functions Use lambdas for one-liners only. For anything complex, define a proper function. Yes: Acceptable but prefer named function: Style Rules Line Length Maximum line length: 80 characters. Exceptions allowed for imports, URLs, and long strings that can't be broken. Indentation Use 4 spaces per indentation level. Never use tabs. …
