What are the collection types we have in Python?

Python provides several built‑in collection types:

• List – ordered, mutable, allows duplicates. Syntax: [1, 2, 3].
• Tuple – ordered, immutable, allows duplicates. Syntax: (1, 2, 3).
• Set – unordered, mutable, no duplicates. Syntax: {1, 2, 3}.
• Dictionary – unordered (Python 3.7+ preserves insertion order), mutable, key‑value pairs. Syntax: {'a': 1, 'b': 2}.
• FrozenSet – immutable set.

Additionally, the collections module offers specialized collections such as namedtuple, deque, defaultdict, and OrderedDict. These extend the basic types with useful semantics for specific use‑cases.
