Q: What will be the output after the following statements?

x = {'A', 'B', 'C'}
y = 'b' in x
print(y)

A. x[1]
B. ['B']
C. True
D. False

Correct Option: D
Remarks:

Explanation: False

Q: What is the output of the following

set1 = {10, 20, 30, 40, 50}
set2 = {60, 70, 10, 30, 40, 80, 20, 50}

print(set1.issubset(set2))
print(set2.issuperset(set1))

A. False False
B. True True

Correct Option: B
Remarks:

Explanation: True True

Q: What is the output of the following set operation

set1 = {"Yellow", "Orange", "Black"}
set2 = {"Orange", "Blue", "Pink"}

set3 = set2.difference(set1)
print(set3)

A. {
B. {
C. {
D. None

Correct Option: B
Remarks:

Explanation: {‘Pink’, ‘Blue’}

The difference() method returns a set that contains the difference between two sets.
Here set3 = set2.difference(set1) so the returned set contains items that exist only in the first set, and not in both sets.

Q: Select all the correct options to remove

A. sampleSet.pop("Orange")
B. sampleSet.discard("Orange")
C. del sampleSet ["Orange"]

Correct Option: B
Remarks:

Explanation: sampleSet.discard("Orange")

The remove() and discard() method removes the specified item from a set.

Q: What is the output of the following

sampleSet = {"Yellow", "Orange", "Black"}
sampleSet.add("Blue")
sampleSet.add("Orange")
print(sampleSet)

A. {
B. {

Correct Option: B
Remarks:

Explanation: {‘Blue’, ‘Orange’, ‘Yellow’, ‘Black’}

Python set doesn’t allow duplicate items.

Q: What is the output of the following

sampleSet = {"Yellow", "Orange", "Black"}
sampleSet.discard("Blue")
print(sampleSet)

A. {
B. KeyError:

Correct Option: A
Remarks:

Explanation: {‘Yellow’, ‘Orange’, ‘Black’}

If the item to remove does not exist in the set, the discard() method will NOT raise an error. If we use remove() method to perform the same operation, we will receive a keyError.

Q: What is the output of the following code

sampleSet = {"Yellow", "Orange", "Black"}
print(sampleSet[1])

A. Yellow
B. Syntax Error
C. Orange

Correct Option: B
Remarks:

Explanation: Syntax Error

We cannot access items in a set by referring to an index because the ‘set’ object does support indexing (the set is unordered). if you try to access items using the index, you will get TypeError: ‘set’ object does not support indexing.

Use a for loop to access set items.

sampleSet = {"Yellow", "Orange", "Black"}
for item in sampleSet:
  print(item)

Q: Select all the correct ways to copy two sets

A. set2 = set1.copy() set2 = set(set1) set2.update(set1)
B. set2 = set1

Correct Option: A
Remarks:

Explanation:

When you set set2= set11, you are making them refer to the same dict object, so when you modify one of them, all references associated with that object reflect the current state of the object. So don’t use the assignment operator to copy the set instead use the copy() method or set() constructor.

Q: The symmetric_difference() method returns a set that contains all items from both sets, but not the items that are present in both sets.

A. False
B. True

Correct Option: B
Remarks:

Explanation: True

Question was not answered

Example:

A = {30, 20, 10}
B = {50, 30, 40}
print(A.symmetric_difference(B))

Output:

{40, 10, 50, 20}

Q: What is the output of the following union operation

set1 = {10, 20, 30, 40}
set2 = {50, 20, "10", 60}

set3 = set1.union(set2)
print(set3)

A. {40, 10, 50, 20, 60, 30}
B. {40,
C. {40, 10,
D. SynatxError: Different types cannot be used with sets

Correct Option: C
Remarks:

Explanation: {40, 10, ’10’, 50, 20, 60, 30}

The union() method returns a new set with all items from both sets by removing duplicates
