A data type consisting of numbers, letters and symbols.

• String
• Integer
• Float
• Boolean

In the picture, the x in "Canvas1.Height x 0.1" is:

• a relational operator

• a logical operator

• an arithmetic operator

• a string

A(n) relational operator is:

• An expression that can be evaluted as TRUE or FALSE. Often used in CONDITIONAL STATEMENTS, such as IF (condition) THEN (action1) ELSE (action2)

• A symbol that represents a compare action for a computer to take. Examples are: ">" (greater than), "<" (less than) and "=" (equal)

• Operators that are used to combine or change Boolean Expressions. The 3 standard operators are AND, OR, and NOT.

• Control block that looks for events to then perform action

A(n) arithmetic operator is:

• Values that a program provides to a function or subroutine

• Type of code to perform a math operation, such as + - * /

• A set of steps to accomplish a task.

• Way to manage complexity, hide details or remove duplication

Python identifies blocks of code by

• BEGIN and END keywords
• { and }
• aligning up the starts of lines (indentation)
• guessing

To repeat a fixed number of times use a

• while loop
• for loop
• if loop
• indentation

If AngryBird.X = 50, AngryBird.Y = 50 and HappyPig.X = 30, HappyPig.Y = 30, what color will be chosen?

• Purple

• Green

• Orange

• Yellow

A(n) float is:

• A precise number by including values after the decimal place
• A programming statement that directs control flow - it uses BOOLEAN expressions to make a choice between different paths (IF (condition) THEN (path1) ELSE (path2)
• A data type that can have only 2 values - TRUE or FALSE
• A whole number, it does not have any digits after a decimal.

Converts a number to a string

• str()
• int()
• parseInt()
• convert

Decides if a string only contains numbers

• isalpha()
• isnumeric()
• int()
• string()
