Unit 5: Lists, Loops, and Traversals MBoyd

List

an ordered collection of elements

Element

an individual value in a list that is assigned a unique index

Index

a common method for referencing the elements in a list or string using numbers

Iteration

a repetitive portion of an algorithm which repeats a specified number of times or until a given condition is met.

infinite loop

occurs when the ending condition will never evaluate to true.

Traversal

the process of accessing each item in a list one at a time

Append

add elements to the end of a list

Data abstraction

manage complexity in programs by giving a collection of data a name without referencing the specific details of the representation.

Loops (iteration statements)

change the sequential flow of control by repeating a set of statements zero or more times, until a stopping condition is met

Logic Error

a mistake in the algorithm or program that causes it to behave incorrectly or unexpectedly.

Simulation

abstractions of more complex objects or phenomena for a specific purpose.

Substring

part of an existing string
