Finally, if you want to be able to go through the key-value pairs, you can use the .items() method.

Modify your for loop to iterate over copper.items() instead of copper.values().

--hints--

You should mmodify your for loop to iterate over copper.items() instead of copper.values().

({ test: () => assert(runPython(`_Node(_code).find_for_loops()[0].find_for_iter().is_equivalent("copper.items()")`)) })
