H466 - Arrays, Records, Tuples and Lists

What is the primary difference between static and dynamic arrays?

• Static arrays can change size during runtime, while dynamic arrays cannot.

• Static arrays have a fixed size, while dynamic arrays can change size during runtime.

• Static arrays are always mutable, while dynamic arrays are immutable.

• Static arrays are only used in Python, while dynamic arrays are used in other languages.

Which of the following is a characteristic of mutable lists in Python?

• They cannot be changed after creation.

• They allow elements to be added, removed, or modified.

• They are faster than immutable lists.

• They are stored in a fixed memory location.

What is a key characteristic of tuples in Python?

• Tuples are mutable and can be changed after creation.

• Tuples are immutable and cannot be changed after creation.

• Tuples can only store elements of the same data type.

• Tuples are slower to access than lists.

Which of the following best describes a record data structure?

• A collection of elements of the same data type.

• A collection of fields, possibly of different data types, typically in a fixed number and sequence.

• A sequence of elements that can be accessed by an index.

• A data structure that only stores numeric values.

Which operation is not typically supported by arrays in Python?

• Accessing an element by index.

• Appending an element to the end.

• Removing an element by value.

• Inserting an element at a specific index.

How do you define a tuple in Python?

• Using square brackets, e.g., `[1, 2, 3]`.

• Using curly braces, e.g., `{1, 2, 3}`.

• Using parentheses, e.g., `(1, 2, 3)`.

• Using angle brackets, e.g., `<1, 2, 3>`.

What is the result of the following Python operation: `len((1, 2, 3, 4))`?

• 3

• 4

• 5

• 6

Which of the following is a valid operation on a list in Python?

• `list.append(5)`

• `list.add(5)`

• `list.insert(5)`

• `list.push(5)`

In Python, which of the following is true about arrays?

• Arrays can only store integers.

• Arrays are always immutable.

• Arrays can store elements of different data types.

• Arrays require the `array` module to be used.

What is the output of the following Python code: `my_tuple = (1, 2, 3); my_tuple[1] = 4`?

• `(1, 4, 3)`

• `(1, 2, 3)`

• An error is raised.

• `(4, 2, 3)`
