Can you list the main data structures used in Python?

Main data structures in Python:

• Lists (list) — ordered mutable collections of elements.
• Tuples (tuple) — ordered immutable collections.
• Sets (set) — unordered collections of unique elements.
• Dictionaries (dict) — collections of key-value pairs.

Additionally, there are specialized structures from the collections module:

• deque — a double-ended queue.
• defaultdict — a dictionary with default values.
• OrderedDict — a dictionary that preserves insertion order.

Example of using a list and a dictionary:

fruits = ['apple', 'banana', 'cherry']
prices = {'apple': 100, 'banana': 80, 'cherry': 120}
