这就是一个井字游戏，尽管它还没有完成，下面的代码是我的整个程序，没有其他的导入或类似的东西，当我有top_left = turn的时候，它的意思是改变顶部的变量top_left为1或2，当变量改变时，它的意思是在左上角或中上角的方格中画一个0为1，为2，你在其中一个方格中得到一个X，由于某些原因，值改变为1或2，但X或0没有画。
global top_left, top_middle, top_right
global middle_left, center, middle_right
global bottom_left, bottom_middle, bottom_right
#these are the variables used to check if someone has put their move their already
#0 = empty
#1 = Circle
#2 = X
top_left = 0
top_middle = 0
top_right = 0
middle_left = 0
center = 0
middle_right = 0
bottom_left = 0
bottom_middle = 0

该
global声明 是一个声明，它对当前整个代码块都有效。这意味着列出的标识符将被解释为 globals。
这意味着，你必须把 global 语句，将全局变量写入全局命名空间的函数中。
将全局声明移动到 mousePressed:
#dectects the quardnates where the mouse clicked and prints them
def mousePressed():
global top_left, top_middle, top_right
global middle_left, center, middle_right
global bottom_left, bottom_middle, bottom_right
println( (mouseX, mouseY) )
#top left square hitbox
if (mouseX > 0 and mouseX < 200) and (mouseY > 0 and mouseY < 200):
top_left = turn
turn_changer()
print("top left")
print(top_left)
#top middle square hitbox
elif (mouseX > 200 and mouseX < 400) and (mouseY > 0 and mouseY < 200):
top_middle = turn
turn_changer()
print(top_middle)
print("top middle")

似乎你已经定义了几个函数，但你没有调用任何一个。当你运行程序时，你的程序如何知道该使用哪个函数？
你需要调用一个或多个函数。试着在你的程序底部添加一个调用，你就会发现它在 "工作"。用引号，因为我会怀疑你会有错误。例如，如果你将调用你的函数 mousePressed()，那么你就会出现一个错误，抱怨说 println 不被定义。确实如此。println 不是一个python函数。同样，你的程序也不会知道 rect() 或 ellipse() 或 line() 如果你不导入它们。
希望这能帮助你
