Python Collections

Collections in Python

• A collection in Python is a data structure that can hold multiple items or variables, allowing for organizing and managing data efficiently.
• Built-in Python collections include lists, tuples, sets, and dictionaries. Any data structure outside of these is not considered a built-in collection.

Types of Collections

• Lists are ordered, mutable collections that allow duplicate elements.
• Tuples are ordered but immutable collections that do not permit changes post-creation.
• Sets are unordered and mutable, allowing for unique elements, meaning duplicates are not permitted.
• Dictionaries are collections of key-value pairs that are mutable, allowing easy retrieval and modification of data via keys.

Mutability of Collections

• Mutable collections can be modified after creation without changing their identity; examples include lists, sets, and dictionaries.
• Immutable collections, like tuples, cannot be altered once created, ensuring data integrity where necessary.

Purpose of Containers in Programming

• Containers group related data, allowing for easy management of collections of values.
• They enable efficient data access, manipulation, and storage, contributing to better software organization and structuring.

Course Coverage

• The course will cover fundamental types of collections including lists, tuples, sets, and dictionaries, exploring their properties, use cases, and differences in mutability.
