To visit both keys and values, prices.items() yields pairs. for item, price in prices.items(): unpacks each pair, preserving insertion order in modern Python. prices.keys() visits just keys; prices.values() visits just values. A dictionary has no numbered key positions.
This is an editable worked demo. Edit main.py, press Run to compare the result, then Submit to check your small change. The next lesson transfers the idea to a different setting.
Change the loop to append the item name rather than its price. Run should print the two item names; then Submit.
prices.items() and append each key to items.
