What components are included in the structure of a dictionary in Python?

In Python, a dictionary (dict) is a data structure that stores key-value pairs. The main components of a dictionary:

• Keys — unique and immutable objects (e.g., strings, numbers, tuples).
• Values — can be any Python objects.

Internally, the dictionary is implemented as a hash table, where keys are hashed for quick access to values. This provides an average complexity of about O(1) for search, insert, and delete operations.

Example of a dictionary:

person = {
    "name": "Ivan",
    "age": 30,
    "city": "Moscow"
}
