What problem does it solve?

This guide helps developers write Python in n8n Code nodes within the platform's constraints, highlighting the critical limitations, safe data access patterns, and correct return formats to avoid common pitfalls.

Core Features & Use Cases

• Enforces no external libraries; use only Python's standard library.
• Documents data access patterns (_input.all(), _input.first(), _input.item, and _node references) and proper webhook payload handling.
• Emphasizes correct return structure (a list of dictionaries with a "json" key) and error-prevention best practices.
• Provides patterns for common transformations, aggregations, and text processing using the standard library.

Quick Start

Open a Python Code node and start applying the guidelines to write safe, standard-library only code using the recommended data-access patterns.
