Iterating with .items()

Question

Accepted Answer

d.items() yields (key, value) tuples in insertion order. Unpacking each tuple into k and v gives you both in one step. This is the most common way to loop over a dict when you need both the key and the value. Without tuple unpacking you'd write 'for item in d.items(): print(item[0], item[1])' - much less readable.
