21 + 2 * 5 + 3
34 since 21 + 2 * 5 + 3 = 21 + 10 + 3 = 31 + 3 = 34
What if statement would print the word "teenager" if the variable age is greater than or equal to 13?
if age >= 13: print("teenager") or if age > 12: print("teenager")
asparagus = "yes" broccoli = "no" Does the following control expression simplify to true or false? asparagus == "no"
false since asparagus == "no" can be rewritten as "yes" == "no" which simplifies to false
4 + 2 ** 3
12 since 4 + 2 ** 3 = 4 + 8 = 12
What is the output? grade = 85 if grade > 70: if grade > 80: print("great") else: print("ok") else: print("poor")
great
What are the 5 steps of the Programming Process in order?
1. Understand 2. Design/Plan 3. Code 4. Test/Debug 5. Document You should be able to explain them in a complete sentences as well!
misspelling a ______________ such as immport causes a syntax error
keyword
What is the output? grade = 95 if grade >= 90: print("A") if grade >= 80: print("B")
A B Both display since two if statements are independent of each other. That is, a single if elif statement was not used.
What line of code sets the variable firstName to the actual first name of our first U.S. president?
firstName = "George"
asparagus = "yes" broccoli = "no" Does the following control expression simplify to true or false? not (asparagus == "no" and broccoli == "no")
true since not (asparagus == "no" and broccoli == "no") can be rewritten as not ("yes" == "no" and "no" == "no") which simplifies to not (false and true) which simplifies further to not (false) which simplifies even further to true
7 // 3
2 since 7 divided by 3 is 2.3333 but the .3333 is truncated or cut off since the // integer division operator is used rather than the / division operator
foo = 6 num = 25 other = 9 Does the following control expression simplify to true or false? num > 0 or (foo < 5 and other == 9)
true since num > 0 or (foo < 5 and other == 9) can be rewritten as 25 > 0 or (6 < 5 and 9 == 9) which is true or (false and true) which simplifies further to true or false which simplifies even further to true
Documentation and notes that are only intended for human computer programmers to read and that are not executed by the computer are known as ____________.
comments
asparagus = "yes" broccoli = "no" Does the following control expression simplify to true or false? broccoli != "yes"
true since broccoli != "yes" can be rewritten as "no" != "yes" which simplifies to true
The int function can convert a string to an ____________ as in this example: age = int(input("Enter your age: "))
integer or number
The first step of the Programming Process is to _______________ the problem.
understand
-1 * (3 + 10)
-13 since -1 * (3 + 10) = -1 * 13 = -13
What line of code sets the variable votingAge to the integer value that is the U.S. voting age?
votingAge = 18
foo = 6 Does the following control expression simplify to true or false? foo <= 6
true since foo <= 6 simplifies to 6 <= 6 which further simplifies to true
What is the output? grade = 75 if grade > 70: if grade > 80: print("great") else: print("ok") else: print("poor")
ok
What is the output of the following code segment? width = 8 base = 4 height = 8 print(width / base * height)
16 since width / base * height = 8 / 4 * 8 = 2 * 8 = 16 Note that the division is performed before multiplication from left to right according to PEMDAS.
What statement must be used at the top of a program to produce turtle graphics?
import turtle
What is the output? grade = 90 if grade >= 90: print("A") elif grade >= 80: print("B")
A
200 % 10
0 since 0 is the remainder of 200 divided by 10
The variable data type used to store text (and also enjoyed by playful kittens) is _____________.
string
What if statement would print the phrase "movie ticket" if the variable age is equal to 13 and the variable money is greater than 12.
if age == 13 and money > 12: print("movie ticket")
The % operator (symbol) is used to compute the ____________ of one integer divided by another integer. For example, 10 % 3 is 1.
remainder
What is the output? grade = 85 if grade >= 90: print("A") elif grade >= 80: print("B")
B since grade >= 90 simplifies to 85 >= 90 which is false so the elif control expression is checked and grade >= 80 simplifies to 85 >= 80 which simplifies to true and therefore print("B") executes
Debugging a program is done during the __________ step of the Programming Process.
4th
What line of code changes the color of a turtle named pen to the color of blue?
pen.color("blue")
The set of rules that determines the priority in which expressions with several operators such as multiplication ( * ) and addition ( + ) is known as the _________________.
order of operations or PEMDAS or GEMDAS
asparagus = "yes" broccoli = "no" Does the following control expression simplify to true or false? asparagus == "yes" and broccoli == "yes"
false since asparagus == "yes" and broccoli == "yes" can be rewritten as "yes" == "yes" and "no" == "yes" which simplifies to true and false which simplifies even further to false
The expression 2 - 4 + 2 simplifies to ____________
0 Note: The subtraction comes first according to PEMDAS since it appears before addition from left to right.
What keyword is used to create a function?
def
What lowercase letter is displayed on the turtle graphic coordinate window? import turtle pen = turtle.Turtle() pen.goto(0, 100) pen.goto(0, 50) pen.goto(50, 50) pen.goto(50, 0)
h
How many parameters (numbers) does the goto function have in its parentheses? example: pen.goto( ??? )
2 example: pen.goto(100, 0)
What if statement would print the word "true" if the variable num is equal to 6?
if num == 6: print("true")
pen
What is the output of the following code segment? hours = 40 rate = 10.99 print(hours * int(rate))
400 since hours * int(rate) = 40 * int(10.99) = 40 * 10 = 400 Note that the int function truncates (cuts off) the decimal places of 10.99. It does not round 10.99 up to 11!
A reserved word in a computer language such as Python that cannot be used as the name of a variable or function is a ___________.
keyword
What is the output of the following code segment? a = "19" b = "610" c = a + b print(c)
19610 or "19610" since a + b is "19" + "610" and string concatenation occurs rather than mathematical addition. Note that 629 does NOT display since a and b are both strings with quotes around them.
6 10 * (16 % 5)
60 since 6 10 * (16 % 5) = 6 10 * 1 = 6 * 10 = 60
Is a vertical or horizontal line displayed by this code segment? import turtle pen = turtle.Turtle() pen.left(90) pen.penup() pen.forward(50) pen.right(90) pen.forward(100)
horizontal
What is the output? grade = 95 if grade >= 80: print("B") elif grade >= 90: print("A")
B A logic error occurs since the grade >= 80 control expression is first checked and, since it is true, "B" is immediately printed!
What number would make the line that connects these two points on a turtle coordinate grid a vertical line? ( _____ , 0) & (40, 100)
40
asparagus = "yes" broccoli = "no" Does the following control expression simplify to true or false? asparagus == "yes" or broccoli == "yes"
true since asparagus == "yes" or broccoli == "yes" can be rewritten as "yes" == "yes" or "no" == "yes" which simplifies to true or false which simplifies even further to true
The str function can convert an integer to a ___________ as in this example: age = 15 print("My age is " + str(age))
string
The # operator (symbol) is used to make a _________________ .
comment or comment statement
14 % 4
2 since the remainder of 14 divided by 4 is 2
24 2 + 3 * 2
57 since 24 2 + 3 * 2 = 24 * 2 + 9 = 48 + 9 = 57
