AttributeError：'str'对象没有属性'set'

Question

This is a simple Tic-Tac-Toe game. When the game is completed, the function gameover() is called and a label (congratulatory message ie playername wins!) has to be displayed on another window. I am trying to achieve this by using a format operator, set() and get() functions.

Error:

Traceback (most recent call last):
File "C:\\Users\\a\\AppData\\Local\\Programs\\Python\\Python37-32\\ZPrograms\\XOXO.py", line 59, in
playerX=winplayX.set()
AttributeError: 'str' object has no attribute 'set'

How do I solve this?

Code:

playerX = StringVar()
playerY = StringVar()
winplayX = StringVar()
winplayY = StringVar()

winplayX= playerX.get()
winplayY= playerY.get()

playerX=winplayX.set()
playerY=winplayY.set()

u=Frame(root)
u.grid(row=1)

playerX_name = Label( u, text="Player X:", font='Times 25 bold', bg='white', fg='black', height=1, width=10)
playerX_name.grid(row=1, column=2)

playerX_name=Entry(u,textvariable=playerX,font="Times 25")
playerX_name.grid(row=1, column=3)

v=Frame(root)
v.grid(row=2)

playerO_name = Label( v, text="Player O:", font='Times 25 bold', bg='white', fg='black', height=1, width=10)
playerO_name.grid(row=2, column=0)

playerO_name = Entry(v,textvariable=playerY,font="Times 25")
playerO_name.grid(row=2, column=3)

def gameover(winflag):
    win= Toplevel()
    win.title("Game Over")
    win.geometry("260x260+614+339")
    global winplayX
    global winplayY

    if  winflag==1:
            wLabel1=Label(win, text="%s Wins!"%winplayX,font='Times 20 bold').place(x=80, y=80)
    elif winflag==2:
            wLabel2=Label(win, text="%s Wins!"%winplayY,font='Times 20 bold').place(x=80, y=80)
    elif winflag==3:
            wLabel3=Label(win, text="It is a tie",font='Times 20 bold').place(x=80, y=80)

If what you are trying to do, is just have the player names be outputted. You can just change this code:

playerX = StringVar()
playerY = StringVar()
winplayX = StringVar()
winplayY = StringVar()

winplayX= playerX.get()
winplayY= playerY.get()

playerX=winplayX.set()
playerY=winplayY.set()

to this:

winplayX = StringVar()
winplayY = StringVar()

winplayX.set("Player1")
winplayY.set("Player2")
