d) all of the mentioned
Explanation: Execute in the shell to verify
2. What is the output when we execute list(“hello”)?
a) [‘h’, ‘e’, ‘l’, ‘l’, ‘o’]
b) [‘hello’]
c) [‘llo’]
d) [‘olleh’]
Explanation: Execute in the shell to verify.
3. Suppose listExample is [‘h’,’e’,’l’,’l’,’o’], what is len(listExample)?
a) 5
b) 4
c) none
d) error
Explanation: Execute in the shell and verify.
4. Suppose list1 is [2445,133,12454,123], what is max(list1)?
a) 2445
b) 133
c) 12454
d) 123

a) 3
b) 5
c) 25
d) 1
Explanation: Min returns the minimum element in the list.
