Choose the type of collection described.
Stella [2.4K]

Answer:

1) List

2) Dictionary

3) Tuple

Explanation:

A list uses square brackets. It is used to store multiple items in just one variable. They are usually changeable and give room for duplicates. You use append to add to the collection.

A dictionary uses curly brackets. You use update to add to the collection. A dictionary is created by placing the elements in curly brackets and separating them with a comma. It is changeable and it does not give room for duplicates.

A tuple uses parentheses. You cannot change it once you create it. It is an ordered list of elements that is finite and can also store multiple items in one variable.
