Week 3: Flow Control

These flashcards cover key vocabulary and concepts from the Python programming lecture focusing on flow control, boolean expressions, loops, conditional statements, and lists.

Boolean expression

A logical statement that is either TRUE or FALSE.

Relational operators

Operators that compare values, such as

Logical operators

Operators that combine Boolean values, such as and, or, and not.

Short-circuit evaluation

A programming technique where the second argument is only evaluated if the first argument is true.

While loop

A loop that repeats as long as a specified condition is true.

Conditional statement

A statement that executes different actions based on whether a condition is true or false.

Chained conditional

Multiple conditions evaluated in sequence, using elif and else statements.

Nested conditional

A conditional statement inside another conditional statement.

List definition

A collection of ordered values that can contain mixed data types.

Accessing list elements

Retrieving items from a list using their index.

Updating list elements

Changing values at specific indices in a list.

Appending elements

Adding an element to the end of a list.

Inserting elements

Adding an element at a specified index in a list.

Removing elements

Deleting elements from a list using methods like pop.

Slicing

Extracting a portion of a list using a range of indices.

Iteration

The process of repeating a set of instructions a specified number of times or until a condition is met.

Iterable object

An object that can produce an iterator, such as lists and strings.

Iterator

An object that enables traversing through a collection.

List comprehension

A concise way to create lists in Python using a single line of code.

Boolean algebra

A branch of algebra where the values of the variables are true and false.

Logic gates

Devices that perform a Boolean function; examples include AND, OR, and NOT.

5 != 6

An example of a true Boolean expression.

if statement format

if condition: action; else: alternative action.

List methods

Functions like append(), pop(), and insert() that manipulate list data.

String as a list

A string is a list of characters in Python.

Variable declaration

The process of creating a variable and assigning it a value.

Input function

A built-in Python function that reads input from the user.

Loop control statements

Statements that control the flow of loops, such as break and continue.

Iteration control variable

A variable that tracks the current iteration of a loop.

List slicing syntax

list[start:stop:step] allows retrieval of items within a range.

Boolean logic

The study of truth values and how they affect program execution.

elif keyword

A shorthand for 'else if' in Python's conditional statements.

Condition evaluation

The process by which Python checks if a condition is true or false.

Function call format

Name of the function followed by parentheses containing arguments.

Boolean variables

Variables that can only hold true or false values.

Comparison operator performance

The efficiency of assessing relationships between values.

While loop condition

The expression that determines if the loop continues or stops.

Logical statement

A statement that can be evaluated as true or false.

Dynamic typing in Python

Type of variable is determined at runtime.

Debugging

The process of identifying and fixing errors in code.

Executing code block

The section of code that runs when a condition is met.

Python list initialization

Creating a new list with specified values.
