Question
1. What will the following code display?
values = [2, 4, 6, 8, 10]
print(values[1:3])
[4,6]
[2,4,6]
[4,6,8]
[2,4]
2. Suppose that myList is [3, 4, 5, 20, 5, 25, 1, 3], what is myList.count(5) ?
0
4
1
2
3.
What is the output of the following code?
>>> a={1,2,3}
>>> b=frozenset([3,4,5])
>>> a-b
{1,2}
Error since the difference between a set and a frozen set cannot be determined
Error because of unsupported operand type for set data type
frozenset({1,2})
