Syntax General

The rules for writing code in a specific programming language

Bug General

A bug is a problem in your code.

Bug

Debugging General

Debugging is fixing a problem in your code.

Debugging

While Loop General

Lets us repeat code as long as something is true.

While Loop

If Statement General

An if statement lets you ask a question to the program and only run code if the answer is true.

If Statement

If Else Statement General

Control structure that lets us run either one section of code or another depending on a test.

If Else Statement

interpreted language General

Translates and executes program code line by line into machine code.

compiled language General

Translates, or “compiles” the entire code into machine code and then runs the program, or sets aside to run later.

Low-Level Language General

A programming language, generally machine code or assembly language, that provides little or no abstraction from a computer's instruction set architecture

High-Level Language General

A programming language has a significant abstraction from the details of computer operation.

Loop General

A loop is a way to repeat code in your program.

Loop

For Loop Python

A for loop lets us repeat code a **fixed number of times.**

Boolean Python

A True or False value

Floating Point Numbers Python

Also called floats, floating point numbers represent real numbers and are written with a decimal point dividing the integer and fractional parts.

Integer Python

A positive or negative whole number.

String Python

A sequence of characters surrounded by quotation marks.

int(string) Python

Converts a string into an integer

str(number) Python

Converts number to text

float(string) Python

Converts a string into a float

Type Conversion Python

The process of converting the value of one data type (integer, string, float, etc.) to another data type is called type conversion.

Escape Sequence General

Escape sequences are characters with special meanings.

Concatenation Python

Adding two strings together using the "+" operator.

methods of an object General

Defines what an object can do.

input() Python

A function that prints a prompt and retrieves text from the user.

Parameters Python

Pieces of information you can give to functions when you define them. When the function is called the arguments are the data you pass into the function's parameters. Parameter is the variable in the declaration of the function. Argument is the actual value of this variable that gets passed to the function.

Mouse Event General

A mouse event is when the user does something with the mouse, like clicking or moving.

Design Process General

A series of steps that help you solve a problem or build something new.

Computer General

Hardware General

The physical components of a computer

motherboard General

A circuit board with ports and sockets used to connect the main devices of a computer.

central processing unit (CPU) General

The core component of a device that accepts and executes instructions.

random access memory (RAM) General

A fast type of computer memory which temporarily stores all the information your device needs right away.

hard drive General

A data storage device that uses magnetic storage and rapidly rotating disks to store and retrieve digital information.

Cloud Computing General

Cloud computing is the on demand availability of computer system resources, especially data storage and computing power, without direct active management by the user.

Information General

Created when a collection of data is organized or structured.

Knowledge General

Pulls meaning from information by analyzing the organized data and generating insights.

Data General

A collection of numbers or data points.

Spreadsheet General

A computer program that helps us organize, manipulate, and analyze data.

Cell General

The intersection of a row and a column.

Row General

A horizontal line of cells.

Column General

A vertical line of cells.

Function General

A built-in formula that performs specific calculations.

Statistics General

The practice or science of collecting and analyzing numerical data.

Mode General

The value that occurs the most.

Statistical question General

A question that could have variability within its answers.

data story Python
