1What is the output of the following ?
sampleSet = {"Yellow", "Orange", "Black"}
sampleSet.add("Blue")
sampleSet.add("Orange")
print(sampleSet)- A{‘Blue’, ‘Orange’, ‘Yellow’, ‘Orange’, ‘Black’}
- B{‘Blue’, ‘Orange’, ‘Yellow’, ‘Black’}
2The union() method returns a new set with all items from both sets by removing duplicates
- AVerdadero
- BFalso
3Select all the correct ways to copy two sets
- Aset2 = set1.copy()
- Bset2 = set1
- Cset2 = set(set1)
- Dset2.update(set1)
4What is the output of the following
sampleSet = {"Yellow", "Orange", "Black"}
sampleSet.discard("Blue")
print(sampleSet)- A{‘Yellow’, ‘Orange’, ‘Black’}
- BKeyError: ‘Blue’
5The symmetric_difference() method returns a set that contains all items from both sets, but not the items that are present in both sets.
- AVerdadero
- BFalso
6What is the output of the following code
aSet = {1, 'PYnative', ['abc', 'xyz'], True}

- B{1, ‘PYnative’, [‘abc’, ‘xyz’], True}
- CTypeError

print(set3)- A{40, 10, 50, 20, 60, 30}
- B{40, ’10’, 50, 20, 60, 30}
- C{40, 10, ’10’, 50, 20, 60, 30}
- DSynatxError: Different types cannot be used with sets
11What is the output of the following set operation
set1 = {"Yellow", "Orange", "Black"}
set2 = {"Orange", "Blue", "Pink"}

- B{‘Pink’, ‘Blue’}
- C{‘Yellow’, ”Black’}
12Select all the correct options to remove “Orange” from the set.
sampleSet = {"Yellow", "Orange", "Black"}- AsampleSet.pop(“Orange”)
- BsampleSet.discard(“Orange”)
- CsampleSet.discard('Orange')
- Ddel sampleSet [“Orange”]
13What is the output of the following
