To write Python in n8n Code nodes safely, use standard library modules only and access incoming items via _input.all(), returning a list of dictionaries containing the json key to ensure proper data transformation.

External Python libraries are not supported in n8n Code nodes; you must restrict your implementation to the Python standard library only to avoid execution errors and maintain reliable data processing.

The correct return format for Python Code nodes in n8n is a properly formatted list of dictionaries, where each dictionary includes the json key containing your transformed data structure.

Access webhook data in n8n Python Code nodes by safely parsing the incoming item payload through _input.all(), applying standard data access patterns to extract and transform the webhook request body.

Use Python in n8n Code nodes for standard library data transformations, but switch to JavaScript when you need external packages, advanced workflow integrations, or complex node interactions beyond basic analytics.

Python Code nodes fail in n8n All Items mode when return formats are incorrect or non-standard library modules are used; ensure you return a valid list of dictionaries with the json key and debug common data access issues.
