This Skill provides guidance and patterns for writing Python code within n8n Code nodes, enabling data transformation and automation tasks directly within your workflows.
_input.all(), _input.first(), and _input.item.ModuleNotFoundError, KeyError, and incorrect return formats.Use the n8n-code-python skill to write a Python script that processes all incoming items and returns them with an added 'processed' field.

To write Python code in n8n workflows, use the Code node and execute scripts for data transformation. Access input data using patterns like `_input.all()` or `_input.first()`, and return the processed items to pass them downstream.
Access input data in an n8n Python Code node using `_input.all()` for all items, `_input.first()` for the initial item, or `_input.item` for the current item. These patterns allow you to manipulate incoming webhook data or aggregate multiple sources effectively.
A Python script in n8n throws a ModuleNotFoundError when importing unavailable libraries. To avoid this error, rely on standard Python libraries available within the n8n environment and follow error prevention best practices for your data manipulation tasks.
Yes, you can use Python to transform webhook data in n8n. By writing scripts within the Code node, you can process incoming webhook payloads, perform complex calculations, aggregate data from multiple sources, and add fields like 'processed' before returning the items.
The correct return format for Python scripts in n8n requires returning a list of dictionaries representing the output items. Avoiding incorrect return formats is a key error prevention practice to ensure your workflow continues passing data downstream without KeyErrors.
