I'm getting TypeError: can only join an iterable in dungeon_game.py

I don't understand why This piece of code is getting the error: "TypeError: can only join an iterable"

-->print("You can move {}".format(", ".join(valid_moves)))

get_moves() returns the iterable, moves = ["LEFT", "RIGHT", "UP", "DOWN"] which is assigned to valid_moves.

any feedback is appreciated. thx.

Just by itself, it seems to work.

I tried it and got "You can move LEFT, RIGHT, UP, DOWN", with no errors.

Perhaps there's something else going on — it might help if you share the whole program.

But be sure to use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down: Or watch this video on code formatting.
