hellos.join(World), you're calling .join() method on hellos, but hellos is a list, list doesn't have this method; moreover, World is unknown to Python interpreter as it hasn't been defined anywhere in the program.

It'd be much simpler to use name + " World" to put two strings together in this challenge.
