Given the code below, what describes the values of x that will cause the code to print “condition true”?

if x >= 5 and x < 20:
    print ("condition true")
print ("All done")

• 5 to 20
• This would be true if it was if x >= 5 and x <= 20:
• 6 to 20
• This would be true if it was if x > 5 and x <= 20:
• 5 to 19
• It will print "condition true" when x is greater than or equal to 5 and less than 20.
• 6 to 19
• This would be true if it was if x > 5 and x < 20:

What is printed when the following code executes?

score = 88
if score >= 90:
    grade = "A"
elif score >= 80:
    grade = "B"
elif score >= 70:
    grade = "C"
elif score >= 60:
    grade = "D"
else:
    grade = "E"
print(grade)

• A
• This would be true if the score was greater than or equal to 90
• B
• Since the score is less than 90 and greater than or equal to 80 "B" will print.
• C
• This would be true if the score was less than 80 and greater than or equal to 70.
• D
• This would be true if the score was less than 70 and greater than or equal to 60.
• E
• This would be true if the score was less than 60.

For what value of num will the following print only “You will meet a new friend.”?

if num < 5 or num > 50:
    print("You will get a treat.")
if num == 5 or num < 0:
    print("You will lose something.")
if num < 10 or num > 40:
    print("You will meet a new friend.")
if num < 20 or num > 60:
    print("You will catch a cold.")
if num >= 20 and num <= 30:
    print("You will ace a test.")

• 3
• This will print several things.
• 25
• This will only print "You will ace a test"
• 45
• This will only print "You will meet a new friend"
• 10
• This will only print "You will catch a cold"

Which of the following is equivalent to the code segment below?

if x > 2:
    x = x * 2
if x > 4:
    x = 0

I.   x = 0
II.  if x > 2:
         x = x * 2
III. if x > 2:
         x = 0
IV.  if x > 2:
         x = 0
     else:
         x = x * 2

• I
• This would always set x to 0 but if x was 1 in the original code it would not change.
• II
• If x is greater than 4 it is reset to 0 in the original code.
• III
• Anytime x is greater than 2 it will be set to 0 in the original code.
• IV
• What if x is negative in the original code?

What is the value of grade when the following code executes and score is 93?

if score >= 90:
    grade = "A"
if score >= 80:
    grade = "B"
if score >= 70:
    grade = "C"
if score >= 60:
    grade = "D"
else
    grade = "E"

• A
• This would be true if the 2nd - 4th if were elif instead.
• B
• This would be true if the score was 83 and the 2nd - 4th if were elif instead.
• C
• This would be true if the score was 73 and the 2nd - 4th if were elif instead.
• D
• Since it is true that 93 is greater than 60 this will set grade to "D"
• E
• This would be true if score was less than 60.
