The easiest solution is to use a hash, which is built into the language.
This is assuming the order in which the entries are stored within the
hash is unimportant. In very many cases this is true.

dict = {}
dict[“aardvark”] = “a”
dict[“badger”] = “b”
p dict

You don’t have to use strings for keys and values; you can use just
about anything you want.
