If a is [1, 2, 3]

1. what is the difference (if any) between a * 3 and [a, a, a]?
2. is a * 3 equivalent to a + a + a?
3. what is the meaning of a[1:1] = 9?
4. what's the difference between a[1:2] = 4 and a[1:1] = 4?

How are the statements lst += "xy" and lst = lst + "xy" different, where lst is a list? Explain.

How are the statements lst = lst + 3 and lst += [3] different, where lst is a list? Explain.

Start with the list [8, 9, 10]. Do the following using list functions:

1. Set the second entry (index 1) to 17
2. Add 4, 5 and 6 to the end of the list
3. Remove the first entry from the list
4. Sort the list
5. Double the list
6. Insert 25 at index 3
