Lesson 8 — Dictionaries
Key and value pairs
A dictionary stores values under named keys, like a real dictionary maps a word to its meaning. Read or set a value with square brackets and its key: user["name"].
Why it matters: dicts are perfect for describing one thing with many properties — a user with a name, age and email.
Tip: use user.get("age") instead of user["age"] to avoid an error when the key might be missing.
