What is a list in Python?

• A collection of items that are ordered and changeable

• A single item in Python

• A collection of items that are ordered and unchangeable

• A collection of items that are unordered and unchangeable

How do you access the elements of a list in Python?

• By using the element's value within curly brackets

• By using the element's position within angle brackets

• By using the element's name within parentheses

• By using the index of the element within square brackets.

What is the difference between a list and a tuple in Python?

• A list can be changed, while a tuple cannot.

• A list is used for numbers, while a tuple is used for strings

• A list and a tuple are the same thing

• A list is immutable, while a tuple is mutable

What are tuples used for in Python?

• Tuples are used to store multiple items in a single variable.

• Tuples are used to create loops in Python.

• Tuples are used for defining classes in Python.

• Tuples are used for mathematical calculations in Python.

How do you create a tuple in Python?

• By using angle brackets and separating the elements with semicolons

• By using curly braces and separating the elements with commas
