为什么我不能将两个变量附加为一个元组

Question

list = []
tuples = ((0,1),(1,1),(2,2),)
x = 0
y = 2
list.append([[], tuples + (x,y)])
print(list)

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

Answer 1

list = []
tuples = ((0,1),(1,1),(2,2),)
x = 0
y = 2
list.append([[], tuples + ((x,y),)])
print(list)
