Confused

Let's create a dictionary that contains the currencies of the various countries along with their country codes. The country code will be the key and the currency the value. Using the following key-value pairs: US : Dollar, UK : Pound, JP : Yen assign them to a constant named currencies.

let currencies["US": "Dollars", "UK": "Pound", "JP", "Yen"]

hey David Curtis was hoping if you can help me with the extra credit question,please. it read: "Create an array of 10 songs where each song is a dictionary. The dictionary contains the following keys: title, artist and album." But confused about it because all the keys in the example took one value. can a key take on more values? and if so how would the syntax look like please?
