Module 04 — Data structures

Concepts

• Lists: indexing, slicing, append/remove/sort
• Tuples: immutability
• Dictionaries: keys, values, items, get
• Sets: uniqueness, union/intersection
• List comprehensions (intro)
• Iterating over structures

Practice prompts

1. Create a list of 5 fruits; print the first and last with indexing.
2. Slice [0, 1, 2, 3, 4, 5] to get [1, 2, 3, 4].
3. Given d = {"a": 1, "b": 2}, print all keys and all values.
4. From two lists, build a set of unique elements combined.
5. Use a list comprehension to make [1, 4, 9, 16, 25] from [1..5].
