Data Structures

Way of organizing data so that it can be accessed more efficiently, “containers” that organize and group data according to type.

List

A collection which is ordered, changeable, and allows duplicate members. Can contain different data types.

Tuple

A collection which is ordered, unchangeable (immutable), and allows duplicate members.

Set

A collection which is unordered, unchangeable, unindexed, and does not allow duplicate members. Used to include membership testing and eliminating duplicate entries and can contain different data types.

Dictionary

A collection which is ordered, changeable, and does not allow duplicate members. Holds the key:value pair and cannot have two items with the same key.

Key

An object which can never change like strings, numbers, tuples, etc.
