Understanding Arrays, Records, Lists, and Tuples

What is a key difference between arrays and lists in Python?

• Arrays store data contiguously, while lists do not.

• Lists store data contiguously, while arrays do not.

• Arrays can store multiple data types, while lists cannot.

• Lists are zero-indexed, while arrays are not.

In a zero-indexed array, what is the index of the third element?

• 3

• 2

• 1

• 0

How does Python handle arrays to make them behave like lists?

• By storing data non-contiguously.

• By using a different indexing system.

• By allowing dynamic resizing of arrays.

• By abstracting the array structure.

What is a two-dimensional array typically visualized as?

• Four

What is a record data structure?

• A collection of unrelated fields with different data types.

• A collection of related fields with different data types.

• A collection of related fields with the same data type.

• A collection of unrelated fields.

What is a key characteristic of tuples in Python?

• They can store multiple data types.

• They are mutable.

• They can grow and shrink in size.

• They are immutable.

How do you add an item to a list in Python?

• Using the append() method.

• Using the add() method.

• Using the insert() method.
