Need help with dictionaries

task 1 states: 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.

we need to create a constant and assign it a dictionary.

you create a constant using let and assign it a value using = followed by the value you want to assign it.

dictionaries look like sets of key value pairs seperated by colons. Multiple key value pairs are separated with commas. a dictionary is enclosed with brackets []

so to create a constant named currencies and assign it the dictionary you would use:

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

task 2 states: Assign the value for key "UK" to a constant named ukCurrency.

we need to retrieve a value from the dictionary using a specific key and assign that value to a constant. you can retrieve values from a dictionary using dictionaryName["keyName"]

so to retrieve the value for the key "UK" and assign it to a constant named ukCurrency you would use:

let ukCurrency = currencies["UK"]

GREAT! THANKS FOR THE HELP!
