Algorithms and Coding Fundamentals: Happy Accelerometer

Concatenation

A joining together of separate items —without changing them—into one place. For example, the concatenation of two strings such as "Hello" and "world!" would return "Hello world!".

Logical Operator

A representation of a logical statement that is used to examine the relationship between two values and determine whether the statement is true or false (Boolean conditionals). Examples of logical operators include AND, OR, and NOT.

Arithmetic Operator

A symbol in code that tells a computer to perform a specific math operation, such as addition, subtraction, multiplication, or division. (+ ¬¬¬- × / ).

Variables

The smallest unit of data storage that a program can use. A variable contains known or unknown information referred to as a "value". Two types of variables are global and local.

Arguments

The values that a program provides to a function or subroutine. Sometimes coding professionals use the terms "argument" and "parameter" interchangeably. In this course, argument is a better choice because Python does not use the term parameter.

Call a procedure

To direct a program to execute or reference a certain procedure. A procedure is a subroutine that is stored only once, but can be called many times in a program to execute when needed.

Debug, Debugging

To identify errors or bugs in computer hardware or programs and fix them.
