OPERATORS

100

What is the difference between "=" and "=="

"=" is assignment
"==" is relational/comparison

200

What is the correct order of operations for relation and boolean operators

Relational
not
and
or

300

Value of a in:

a = 3             b = 2             c = 7

a += c

a *= b

a = a**3

8000

400

Convert this interval notation to python code:

if x is in ( - infinity, 10] U [30 , 50)

if (x <= 10) or (x>= 30 and x<50)

500

What is the output of this code

a = 1

b = 3

c = 5

math = int(c // 5 ** b - a * 0.5)

print(math)

0

IF STATEMENTS

100

If statement used when checking conditions sequentially

if-elif-else

200

What kind of if statement is this:

if citizenship == True:

    if age >= 18:

        print("You are eligible to vote")

Nested if

300

Is there an error? If not, what is the output:

x = 0

if x = 5:

    print("Five")

Error "x=5" needs to be "x==5"

400

Output of:

a = 15

if not(a != 30 or a>15):

    print("True")

else:

    print("False")

False

500

predict the output:

GPA = 3.5

credit = 18

if GPA >=2.0:

    standing = "In Good Standing"

    if GPA >= 3.5 and credit >= 12:

        standing = "Dean's List"

        if GPA >= 3.9 and credit >= 15:

            standing = "President's List"

print(standing

Dean's list

LOOPS

100

When would you use a FOR LOOP

when you have a known number of iterations

200

What does "break" do

immediately stops the loop it is in

300

What is the output:

i = 0

while i < 10:

    print(i*2)

Infinite Loop

400

What is the output:

for i in range(1,5,2):

    value = i**2 

    print(value)

1

9

500

How many times does this loop run

count = 0

for i in range(5):

    for j in range(i):

        count += 1

print(count)

10

VARIABLES

100

Convert 5.8 to a integer

int(5.8) = 5

200

Is there an error? If so, where?

The error of the code:

(int("73.5") - float("2")) * 5

int("73.5")

300

Would this result in an error? If no, what is the result?

mystring = "hi"

print(bool(mystring))

No error

output: True

400

Output of:

(float("3.2") + int("4")) / 2

"3.6"

500

What is the output:

from math import*

number = float(bool("True")+15/3*e**(bool()))

print(number)

6.0

LISTS

100

What list operator is used to convert a list to a string with "," as a separator

",".join(list)

200

What does c represent in:

myList[a:b:c]

Step size

300

What is the output of:

mylist = [100,32,43,25,1,82]

num = mylist.pop(3)

print(num*4)

100

400

What is the output of this code: 

newlist = ["a","b","c","d","e","f"]

newlist[1:5]=["x","y"]

print(newlist)

['a', 'x', 'y', 'f']

500

What is the output of this code

list1 = [0,1,2,3,4,5]

list2 = [6,7,8,9,10]

for i in range(len(list2)):

    list1.append(list2[i])

print(list1)

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
