Exercise

Concatenate Lists

The triple-colon operator (:::) concatenates lists to create a new, combined list.

In Twenty-One, there are two major organizations that host competitive tournaments: the National Twenty-One Assocation (NTOA) and EuroTO, based in North America and Europe, respectively. Each league has a list of venues where they host their tournaments, venuesNTOA and venuesEuroTO. Recently, there was a merger of the organizations that made Twenty-One an overseas endeavor. NTOA and EuroTO were combined to create Twenty-One World. That means the list of venues must be combined, as tournaments will be played in both continents now.

In this exercise, you'll use the concatenation operator (:::) to create a new, combined venue list for Twenty-One World.
