CSE 1321 Module 4: Tuples, Lists, and Dictionaries

These flashcards cover key vocabulary and concepts related to tuples, lists, and dictionaries in Python.

Tuple

An immutable sequence of values that can mix data types and may contain nested tuples.

List

A mutable sequence of values that can mix data types and may contain nested lists.

Dictionary

A mapping between keys and values, where items are stored as key-value pairs.

Immutable

A property of tuples meaning that once created, their elements cannot be changed.

Indexing

Accessing elements of sequences (like tuples and lists) using their position.

Slicing

Creating a new tuple or list by extracting a portion of it without changing the original.

Concatenation

Combining two tuples or lists into a new tuple or list using the + operator.

Membership Test

Using the 'in' keyword to check if an item exists in a tuple, list, or dictionary.

Zip Function

A built-in function that combines two or more sequences into a list of tuples.

Insert Method

A list method that adds an element at a specified position.

Append Method

A list method that adds an element to the end of a list.

Extend Method

A list method that adds elements from another list to the end of the existing list.

Join Method

Concatenates a sequence of strings into a single string with a specified separator.

Split Method

Divides a string into a list based on a specified delimiter.

Keys Method

Returns a list of the keys in a dictionary.

Values Method

Returns a list of the values in a dictionary.

Items Method

Returns a list of the key-value pairs in a dictionary as tuples.
