So I'm trying to concatenate two lists in a function. I'm defining the function with two arguments, as instructed, and returning them added together. I can't see anything wrong with the syntax but it refuses to pass it, saying 'SyntaxError: invalid syntax', with the ^ pointing to the 's(' on the function defining line.
m = [1, 2, 3] n = [4, 5, 6] # Add your code here! dev join_lists(x, y): return x + y print join_lists(m, n) # You want this to print [1, 2, 3, 4, 5, 6]
