A dictionary in Python is a collection of key-value pairs, where each key is unique and maps to a corresponding value.

• Keys must be immutable objects (e.g. strings, numbers, tuples).

• Values can be of any data type (e.g. strings, numbers, lists, dictionaries).

• Access values by referencing the key (e.g. my_dict['key']).

• Example: {'name': 'John', 'age': 30, 'city': 'New York'}

List is mutable, tuple is immutable in Python.

• List uses square brackets [], tuple uses parentheses ().

• Elements in list can be changed, tuple elements are fixed.

• List is slower than tuple due to mutability.

• List is used for dynamic data, tuple for fixed data.

• Example: list_example = [1, 2, 3], tuple_example = (4, 5, 6)
