a syntactic unit of an imperative programming language that expresses some action to be carried out.
speed()
changes how fast Tracy moves
Commands
Instructions that you give to a computer for it to carry out an action. Commands are either typed by using a keyboard or are chosen from a menu.

def function_name():
Function header format is:
circle()
a command that will get Tracy to draw a circle
variable_name = int(input("text prompt"))
advanced circle( , , ) three parts
function_name()
Format for calling functions is:
penup()
picks the turtle pen up
pendown()
puts the turtle pen down
variable_name = value
Interpreter Program
Understands the instructions you write in the Python language.
Top Down Design
a problem solving approach in which you break down a system to gain insight into the sub-systems that make it up.
for I in range()
used to start a loop
Variables
Any measurable conditions, events, characteristics, or behaviors that are controlled or observed in a study.
interpreted
Explain the meaning of.
call
to call.
Python
Python is an easy-to-learn, general-purpose, high-level language that has sophisticated capabilities and can operate as both a procedural and object-oriented language.
defining a variable
Choosing a variable and deciding what the variable represents.
int ()
A native type representing the integers, which are positive whole numbers and their opposites.
pensize()
changes the size of the pen
forward()
a command that will move Tracy forward
source files or source code
Source code is the set of instructions and statements written by a programmer using a computer programming language.
user input
Methods created/used to receive data from a user.
loops
a loop is used to repeat code in your program
classic computer science
a series of books that helps software developers learn several problem solving techniques.
Command Prompt
Text prompt for entering commands.
Assigning a variable
Give it a value that matches its data type, uses an assignment operator (=).
end_fill()
ends the begin_fill() function
setposition(x,y)
moves Tracy to the written position
terminal
Causing or forming an end.
right()
rotates Tracy right
Integer
All whole numbers (both positive and negative) and zero.
Syntax
Sentence structure.
comments
Using descriptive text to explain portions of code. Comments do not change the way a robot behaves, but are important for the programmer to remember what the code does.
left()
rotates Tracy left
user input as a number
variable_name = input("text prompt")
Integrated Development Environment (IDE)
Provides a developer with a way to create a program, run the program, and debug the program all within one application.
