{5,6,7,8,10,11}
{7,8}
Error as unsupported operand type of set data type
{5,6,10,11}
Question 2: What will be the output of the following Python code?
>>> s={5,6} >>> s*3
Error as unsupported operand type for set data type
{5,6,5,6,5,6}
{5,6}
Error as multiplication creates duplicate elements which isn’t allowed
Question 4: What will be the output of the following Python code?
>>> a={3,4,5} >>> b={5,6,7} >>> a|b
Invalid operation
{3, 4, 5, 6, 7}
{5}
{3,4,6,7}
Question 5: Is the following Python code valid?
a={3,4,{7,5}} print(a[2][0])
Yes, 7 is printed
Error, elements of a set can’t be printed
Error, subsets aren’t allowed

Allows duplicate values
Data type with unordered values
Immutable data type
Question 7: What is the syntax of the following Python code?
>>> a=frozenset(set([5,6,7])) >>> a
{5,6,7}
frozenset({5,6,7})
Error, not possible to convert set into frozenset
Syntax error
Question 8: Is the following Python code valid?
>>> a=frozenset([5,6,7]) >>> a >>> a.add(5)
Yes, now a is {5,5,6,7}
No, frozen set is immutable
No, invalid syntax for add method
Yes, now a is {5,6,7}
