To write Python in n8n Code nodes, access webhook payloads under the body key and use _input or _json to read data. Return a deterministic list of dictionaries with a json key to ensure safe outputs.

No, n8n Code nodes restrict Python to the standard library only. You must avoid external imports and unsafe operations, relying on standard modules for data transformation and aggregation tasks.

The correct return structure for Python in n8n is a list of dictionaries containing a json key. This deterministic format ensures downstream nodes properly parse the transformed data from your Code node.

Access item data inside an n8n Python Code node using _input and _json variables. Use safe dictionary access methods like .get() to handle missing keys and prevent runtime errors during per-item processing.

Python Code nodes fail if the return structure is incorrect or if code uses external imports. Ensure you return a deterministic list of dictionaries with a json key and use only the standard library.

Yes, n8n supports Python for data transformation and aggregation within Code nodes. You can leverage n8n helper syntax like _input and _node while using standard library modules to process items explicitly.
