Can you list the main data structures and briefly describe their use?

Main data structures in Python and their applications:

• List (list) — an ordered mutable collection of elements. Used for storing sequences that require quick access by index and the ability to modify.

• Tuple (tuple) — an ordered immutable collection. Suitable for storing fixed sets of data.

• Set (set) — an unordered collection of unique elements. Used for operations involving uniqueness, union, intersection.

• Dictionary (dict) — an unordered collection of key-value pairs. Allows quick search, addition, and removal of elements by key.

Example of using a list and a dictionary:

fruits = ["apple", "banana", "cherry"]  # list
prices = {"apple": 100, "banana": 80}  # dictionary
print(fruits[1])  # banana
print(prices["apple"])  # 100
