True.
Go back to Question 13
False. The actual output is shown in Figure 4 . While it is possible to extract and print an element from a tuple using square-bracket indexing, tuple indicesare zero based and the index shown in Listing 2 is out of range.

Go back to Question 11
False. From a syntax viewpoint, you typically create a tuple by placing a sequence of items inside a pair of enclosing parentheses and separating them by commas.
However, and this is important, the parentheses can be omitted when such omission will not lead to ambiguity.
Go back to Question 10
True.
Go back to Question 9
False. You can do just about anything with a tuple that you can do with a list, taking into account the fact that the tuple is immutable . Therefore, those list operations that change the value of a list in place cannotbe performed on a tuple. For example, you cannot call the append method on a tuple as you can on a list.
Go back to Question 8
False. While a tuple itself cannot be changed in place, the values contained in the objects that are referred to by the contents of the tuple can be changed (assuming that those objects are mutable) .
Go back to Question 7
True.
Go back to Question 6
True.
Go back to Question 5
False. Tuples are normally written as a sequence of items contained in parentheses.
Go back to Question 4
True.
Go back to Question 3
True.
Go back to Question 2
True. A tuple is immutable .
Go back to Question 1
