Hey Allison Seim, looking closer, morse_dict uses curly brackets { }, instead of parens ( ), which makes it a dict Rather than a tuple

You can look up a letter in the dict using morse_dict[char] where char is the letter to wish to look up.

More on dict in the docs.

You won’t need to call the morse_code function in your solution.

Post back if you need more help. Good luck!!!
