This document defines key programming concepts used in Python including programs, debugging, editors, stages, sprites, pixels, comments, parameters, dot notation, syntax, casting, strings, integers, variables, lists, data types, nesting, loops, if statements, indexes, functions, events, and refactoring. It provides brief 1-2 sentence definitions for each term to concisely explain their meaning in the context of Python programming.

1. Python Word
Wall

2. PART 1

3. Program
A set of commands that run in
order from top to bottom.

4. Debugging
Finding and fixing the error or
bug in a program.

5. Editor
The area where all commands
are typed.

6. Stage
The area where the visual output
of a program is displayed.
The Codesters stage is an x, y
coordinate plane.

7. Sprite
An object on the stage, like a
character or shape, that can
be given commands.

8. Pixel
The unit of measurement on
the stage.

9. Comment
A line in code that is used to
provide information about the
code.
It is ignored by the program and
does not run.

10. Parameter
Data that controls how a
command runs

11. Dot Notation
Using a sprite’s name in
order to give it a
command.

12. Syntax
The rules that define the
ways a program must
be written.

13. Casting
Changing the data type of a
variable.

14. String
A letter, word, or sentence.
Strings appear green on the
stage.

15. Integer
Any number that is not a
decimal or fraction.
Integers appear blue on the
stage.

16. Variable
A name that stores a value.

17. List
A name that stores a group of
values.

18. Data Type
A name that defines the kind
of information a variable holds.

19. Nesting
Indentation that controls what
commands belong to what
blocks of code.

20. Loop
A block of code containing
commands that will be run
more than once.

21. If Statement
A block of code containing
commands that will only be
run if a certain condition is
met.

22. PART 2

23. Index
The number that refers to a
single item’s place inside a
list.

24. Function
A named block of code
containing commands that will
run when the function is
called.

25. Parameter
A value passed into a function
or command that controls how
that function or command is
run.

26. Float
Any number that is a decimal
or fraction.
Floats appear blue in the
editor.

27. Event
A named block of code
containing commands that will
run when a certain action
happens on the stage.

28. Refactoring
The process of taking a
program or piece of code and
editing it to improve its
structure.
