Learning goals

  • Use sorted() to get a new sorted list and .sort() to sort in place.
  • Reverse a list in place with .reverse().
  • Remove items by value (.remove()) or by index (.pop()).
  • Find positions with .index() and count occurrences with .count().
  • Avoid the classic bug: x = lst.sort() returns None.
  • Sort descending with sorted(lst, reverse=True).
