In the editor we have a dictionary that contains a three letter country code as a key and that country's capital city as

@walterfernandez What you need to do here is use a switch statement. I would suggest going back to this video if you have any trouble. The correct code is below:

// The for in loop, goes through all items in the dictionary.
// The switch statement finds the matching case and appends the value to the correct array
for (key, value) in world {
    // Enter your code below
    switch key {
    case "BEL", "LIE", "BGR": europeanCapitals.append(value)
    case "IND", "VNM": asianCapitals.append(value)
    default: otherCapitals.append(value)
    }
    // End code
}
