title: Why can I not append two variables as a tuple
body: <pre><code>list = []
  tuples = ((0,1),(1,1),(2,2),)
  x = 0
  y = 2
  list.append([[], tuples + (x,y)])
  print(list)
  </code></pre>
  
  <p>Im using This code as part of a tic tac toe AI to construct a tree however when appending this new list to the main list the tuples value reads as ((0,1),(1,1),(2,2),0,2). I intend for the x and y variables to be as part of a single tuple like so:((0,1),(1,1),(2,2),(0,2))
  What am I doing wrong here? thank you in advance</p>
