Test your knowledge: Python zip

Review

1. What does zip([1, 2], ["a", "b"]) produce when iterated?

   Each produced tuple contains one item from each input iterable at the same index.
2. What happens with zip([1, 2, 3], [10, 20]) by default?

   Without strict=True, zip stops when the shortest iterable is exhausted and ignores remaining values from longer inputs.
3. Which behavior is provided by zip(a, b, strict=True) when the input lengths differ?

   strict=True keeps normal pairing but raises ValueError when one iterable is exhausted before the others.
4. What does list(zip(["Ada", "Grace"])) contain?

   A single iterable produces an iterator of one-item tuples.
5. Which expression separates [("Ada", 10), ("Grace", 20)] into the names and scores sequences?

   zip(*pairs) passes the two positions from each pair as separate iterables to zip, which separates the columns.
