print(numbers[i])
Rewrite this loop so it prints every value in numbers, including the first one.
numbers = [1, 2, 3, 4]
for i in range(len(numbers)):
print(numbers[i])
Start range at 0 with range(len(numbers)) so every index is printed.

x = 3
if x = 3:
print("Three")

Use == for comparison in the if condition instead of =
x = 3
if x == 3:
print("Three")

B.18
C.17
D.14
A.16
for i in range(5)
print(i)
This loop has a bug. Rewrite the whole loop so it runs correctly and prints 0 through 4.
You need a colon after range(5) and print(i) indented inside the loop.
for i in range(5):
print(i)
pets list

colors list
"red""pink""orange"
colors = ["red", "pink", "orange"] # About append()
Which statement about append() is true?
A.append() creates a brand-new list and leaves the original unchanged.
B.append() adds a new item to the end of the existing list and changes that list.
C.append() adds a new item to the front of the list.
D.append() only works on lists of numbers.
B.append() adds a new item to the end of the existing list and changes that list.
names list
"Sam" "Alex" "Jordan" "Bella"

print(names[-1])
After sorting, what does this code print?
A."Jordan"

C."Sam"
nums list
8 10 12 14 16 18
nums = [8, 10, 12, 14, 16, 18] a = 0 b = 3 index = a + b
print(nums[index])
What number does this code print?
14
count = 0
while count < 3
print(count)
count = count + 1
Fix this while-loop so it runs without errors and prints 0, 1, 2.
Add the colon after while count < 3 and keep the body indented.
count = 0
while count < 3:
print(count)
count = count + 1

What does this code print?
A.["yellow", "white", "orange", "yellow"] B."yellow" C.None D.It causes an error
C.None
scores list
40 22 34 28
scores = [40, 22, 34, 28] scores.sort() print(scores)

A.[40, 22, 34, 28]
B.[22, 28, 34, 40]
C.[22, 38, 28, 40]
B.[22, 28, 34, 40]
nums list
8 10 12 14 16 18
nums = [8, 10, 12, 14, 16, 18] a = len(nums) b = 2 index = a - b print(nums[index])
What number does this code print?
16
numbers = [1, 2, 3]
for n in numbers:
print(n)
Indent this for-loop correctly so it prints every number in the list.
The print(n) line must be indented so it is inside the for-loop.
numbers = [1, 2, 3]
for n in numbers:
print(n)
