Can you explain the main data structures used in Python?

In Python, there are several core data structures widely used for storing and processing data:

• Lists (list) — ordered mutable collections that can contain elements of different types. They allow adding, removing, and modifying elements.

fruits = ['apple', 'banana', 'cherry']
fruits.append('orange')

• Tuples (tuple) — ordered immutable collections. Used when you need to guarantee that data will not change.

point = (10, 20)

• Sets (set) — unordered collections of unique elements. Useful for operations involving uniqueness and sets.

unique_numbers = {1, 2, 3, 2}  # will be {1, 2, 3}

• Dictionaries (dict) — unordered collections of key-value pairs. Very convenient for quick access by key.

person = {'name': 'Ivan', 'age': 30}
print(person['name'])  # Ivan

These data structures cover most tasks related to data storage and organization in Python.
