The union() method returns a new set with all items from both sets by removing duplicates
Select all the correct ways to copy two sets

set2.update(set1)
What is the output of the following
sampleSet = {"Yellow", "Orange", "Black"} sampleSet.discard("Blue") print(sampleSet)
{‘Yellow’, ‘Orange’, ‘Black’}
KeyError: ‘Blue’
The symmetric_difference() method returns a set that contains all items from both sets, but not the items that are present in both sets.
What is the output of the following code

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)
{40, 10, 50, 20, 60, 30}
{40, ’10’, 50, 20, 60, 30}
{40, 10, ’10’, 50, 20, 60, 30}
SynatxError: Different types cannot be used with sets
What is the output of the following set operation
set3 = set2.difference(set1) print(set3)
{‘Yellow’, ”Black’, ‘Pink’, ‘Blue’}
{‘Pink’, ‘Blue’}
{‘Yellow’, ”Black’}
Select all the correct options to remove “Orange” from the set.
sampleSet = {"Yellow", "Orange", "Black"}
sampleSet.pop(“Orange”)
sampleSet.discard(“Orange”)
sampleSet.discard('Orange')
del sampleSet [“Orange”]
set1 = {10, 20, 30, 40, 50} set2 = {60, 70, 10, 30, 40, 80, 20, 50}
print(set1.issubset(set2)) print(set2.issuperset(set1))

sampleSet = {"Yellow", "Orange", "Black"} sampleSet.update(["Blue", "Green", "Red"]) print(sampleSet)
{‘Yellow’, ‘Orange’, ‘Red’, ‘Black’, ‘Green’, ‘Blue’}
{‘Yellow’, ‘Orange’, ‘Black’, [“Blue”, “Green”, “Red”]}
TypeError: update() doesn’t allow list as a argument.
aSet = {1, 'PYnative', ('abc', 'xyz'), True} print(aSet)
{‘PYnative’, 1, (‘abc’, ‘xyz’), True}
{‘PYnative’, 1, (‘abc’, ‘xyz’)}
