Dictionary items are ordered, changeable, and does not allow duplicates.

Let's understand each of the points:

• Ordered - it means that the items have a defined order, and that order will not change.
• Changeable - it means that we can change, add or remove items after the dictionary has been created.
• No duplicates - dictionaries cannot have two items with the same key.

thisdict = {
  "brand": "Ford",
  "model": "Mustang",
  "year": 1964,
  "year": 2020
}

thisdict dictionary will hold the value 2020 under the key "year".
