			'Runs in a locked-down native Python sandbox. NO imports: both allowlists (N8N_RUNNERS_STDLIB_ALLOW for standard-library modules, N8N_RUNNERS_EXTERNAL_ALLOW for packages) are empty by default, so `import re`, `import json`, `import math`, `import datetime`, `import pandas` and relative imports all FAIL at runtime with "Import of ... is disallowed". Write import-free Python using builtins and str/list/dict methods, or set language to javaScript when the task genuinely needs a library. NO network access either: requests, urllib, httpx and other HTTP libraries are unavailable — use the HTTP Request node and process its output in this node instead. The ONLY globals are _items (runOnceForAllItems mode ONLY), _item (runOnceForEachItem mode ONLY) and print(); reading the accessor belonging to the other mode raises NameError. There are no cross-node helpers either — _("Node Name"), _input, _json, _today and _jmespath are all undefined, so read data from the connected upstream node only.',
