What is the difference between Python (Beta) and Python (Native) modes?

Python (Beta) is recommended as it includes n8n helpers like _input and _now. Python (Native) provides a more limited environment using only _items and _item variables.

What is the mandatory return format for Python in n8n?

You must always return a list of dictionaries where the data is nested under a 'json' key, for example: return [{'json': {'myField': 'myValue'}}].

How do I access webhook data in an n8n Python node?

Webhook data is typically nested under the 'body' property. Use _json['body']['field_name'] or the safer _json.get('body', {}).get('field_name') to access it.

Can I use external libraries like Pandas or Requests in n8n Python nodes?

No, the n8n Python environment is limited to the standard library. You should use n8n's native HTTP Request nodes for API calls or use JavaScript nodes if you need specific npm packages.

Guides developers in writing optimized Python scripts for n8n Code nodes while navigating data structures and environment limitations.

This skill provides expert-level guidance for implementing Python logic within n8n automation workflows. It helps developers master n8n-specific syntax like _input, _json, and _node, while enforcing critical return format requirements to ensure workflow stability. The skill is essential for users who prefer Python for complex data manipulation or statistical analysis, providing workarounds for the environment's lack of external libraries by leveraging the Python standard library effectively.
