Guido van Rossum
Creator of Python
Function
A relation in which each element of the domain is paired with exactly one element of the range
Variables
factors that change in an experiment
Assigning a Variable
Assigning to a variable is updating the variable's value
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.
Classic computer science
is study of computers it includes software and hardware
right()
turns right
User input as a number
int(
Defining a variable
Choosing a variable and deciding what the variable represents.
left()
turns left
advanced circle( , , ) three parts
draws a more advanced circle
Python Software Foundation
A nonprofit organization devoted to the Python programming language, launched on March 6, 2001.
Interpreted
Understood
variable_name = input("text prompt")
inputs text into the code
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.
for i in range()
to loop a set of code
color()
changes the color of the picture being drawn by the turtle
speed()
changes the speed of which the turtle draws the code
variable_name = int(input("text prompt"))
can call a text onto the code (asks a question)
Python
is an interpreted, high-level, general-purpose programming language.
circle()
draws a circle
Argument
a statement of the meaning or main point of a literary work
Functions
A prewritten formula that provides a shortcut to common calculations
end_fill()
Remember the ending point for a filled polygon
Parameters
Extra bits of information that you can pass into a function to customize it
function_name()
Format for calling functions is:
penup()
picks the turtle pen up
Source Code
Contains instructions written by a programmer specifying the actions to be performed by computer software
Syntax
The arrangement of words and phrases to create well-formed sentences in a language.
backward()
moves backwards from the direction you are facing
pensize()
changes the size of the pen
pendown()
puts the turtle pen down
Source Files
The java files that comprise your program.
int()
internal, interior
Command Prompt
Understands the instructions you write in the Python language
Call
To call
def function_name():
Function header format is:
#
adds a comment
Integer
All whole numbers (both positive and negative) and zero.
setposition(x,y)
moves the turtle to a set position
Naming Guidelines Funtcions
Avoid names longer than 25 characters if exposed publicly.
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.
Top Down Design
Starting with a broad concept and breaking it down into smaller and smaller pieces.
Terminal
Causing or forming an end
begin_fill()
Remember the starting point for a filled polygon
Code Statements
A statement is a syntactic unit of an imperative programming language that expresses some action to be carried out.
Loops
A loop is used to repeat code in your program.
Interpreter Program
Understands the instructions you write in the Python language
Cross-platform
In computing, cross-platform software is computer software that is implemented on multiple computing platforms.
forward()
moves forward in the direction you are facing
Section 2
(50 cards)
if condition: commands
if something is correct then another thing is perfomed
def function_name(parameters)
defining what the function is with the name and all of that
Double For Loop
Double-loop learning entails the modification of goals or decision-making rules in the light of experience. The first loop uses the goals or decision-making rules, the second loop enables their modification, hence "double-loop".
if/Else Statements
An if-else statement checks to see if a condition is met or true, if the condition is met the program runs one set of code. If the condition is not met a different set of code will be run.
Mathematical Operators
Symbols used in mathematical operations: + for addition, - for subtraction, * for multiplication, / for division, and ^ for exponentiation.
In function definition
The place where you assign a series of actions to one easy to remember name
Scope
instrument for visual examination
Input Function
How the player will enter text into the program through the keyboard
Exponent
A mathematical notation indicating the number of times a quantity is multiplied by itself.
else:
Another way of saying "Otherwise"
Namespaces
are the databases of information needed to resolve domain names and IP addresses
if Statements
The common programming structure that implements "conditional statements".
iteration
the repetition of a process or utterance.
elif condition:
If you have multiple elif then you can utilize dictionary data type in python.
function_name (arguments)
assigning the name in the arguement
float
A native type representing rational numbers to limited precision.
Subtraction
An operation in which we take away 1 number from another to get a smaller number
While Loops
used to repeat actions without the player needing to write the same lines of code over and over
Range Function
The set of all possible output values of a function
for i in range (ending_num)
for i in range (ending_num)
Type Function
tells us whether the number is int or float
int
A native type representing the integers, which are positive whole numbers and their opposites.
Booleans
having two possible values called "true" and "false."
Round Function
The ROUND() function is used to round a numeric field to the number of decimals specified. NOTE: Many database systems have adopted the IEEE 754 standard for arithmetic operations, according to which the default rounding behavior is "round half to even." In this scheme, .5 is rounded to the nearest even integer. So, both 11.5 and 12.5 would be rounded to 12. SELECT ROUND(column_name,decimals) FROM table_name;
Venn Diagram
A diagram that uses circles to display elements of different sets. Overlapping circles show common elements.
Not Equal to
Relational operator used to determine if one value is not equal to another.
Function Composition
Using the output of one function as the input of another function
Greater Than or Equal to
a value that is "at least" as big as another value has a closed circle
Division
division
for i in range(starting_num, ending_num, increase_by):
how much the code runs, stops, and then increases by
In function call
The piece of code that you add to a program to indicate that the program should run the code inside a function at a certain time.
Assignment Statement
Uses the equal sign to give the object property on the left of the equal sign the value on the right of the equal sign.
while condition: commands to perform
while the code is running there are multiple things you can do to it and can do an infinite loop
str function
converts value to string
Less Than or Equal to
a value that is "at most" as big as another value has a closed circle
Addition
in addition
Continue Function
The continue statement in Python returns the control to the beginning of the while loop. The continue statement rejects all the remaining statements in the current iteration of the loop and moves the control back to the top of the loop. The continue statement can be used in both while and for loops.
Print Statement
An instruction that causes the Python interpreter to display a value on the screen.
Concatenation
Attaching two things side-by-side, frequently strings of text.
Operators
The symbols with which you can specify the type of calculation you want to perform in an Excel formula.
greater than
used to compare two numbers when the first number is larger than the second number.
clear()
To remove all of the formatting applied to a cell or range of cells.
Less Than
Less than is used to compare two numbers when the first number is smaller than the second number.
Type (element)
determined by the number of protons
Crossplatform
Software that can run on multiple types of computer systems.
Break Function
Python break statement Thebreakstatement terminates the loop containing it. Control of the program flows to the statement immediately after the body of the loop. Ifbreakstatement is inside a nested loop (loop inside another loop),breakwill terminate the innermost loop.
multiplication
An operation used for the shortening of repeated addition
Modulus
The number of states through which a counter sequences before repeating.
Equal to
having the same value
Truth Tables
tables that summarize how the computer evaluates the logical operators in an expression
