Q: Suppose listExample is [3, 4, 5, 20, 5, 25, 1, 3], what is list1 after listExample.pop()?
A. [3, 4, 5, 20, 5, 25, 1]
B. [1, 3, 3, 4, 5, 5, 20, 25]
C. [3, 5, 20, 5, 25, 1, 3]
D. [1, 3, 4, 5, 20, 5, 25]

Q: What will be the output of the following Python code?
>>>"Welcome to Python".split()
A. [“Welcome”, “to”, “Python”]
B. (“Welcome”, “to”, “Python”)
C. {“Welcome”, “to”, “Python”}

Q: What will be the output of the following Python code?
myList = [1, 5, 5, 5, 5, 1]
max = myList[0]
indexOfMax = 0
for i in range(1, len(myList)):
if myList[i] > max:
max = myList[i]
indexOfMax = i
>>>print(indexOfMax)
A. 1
B. 2
C. 3
D. 4
Solution: First time the highest number is encountered is at index 1.
Q: What will be the output of the following Python code?
myList = [1, 2, 3, 4, 5, 6]
for i in range(1, 6):
myList[i - 1] = myList[i]
for i in range(0, 6):
print(myList[i], end = " ")
A. 2 3 4 5 6 1
B. 6 1 2 3 4 5
C. 2 3 4 5 6 6
D. 1 1 2 3 4 5
Solution: Execute in the shell to verify.
Q: What will be the output of the following Python code?
>>>list1 = [1, 3]
>>>list2 = list1
>>>list1[0] = 4
>>>print(list2)
A. [1, 3]
B. [4, 3]
C. [1, 4]
D. [1, 3, 4]
Solution: Lists should be copied by executing [:] operation.
