Я сделал несколько изменений: как сказал Брайан Оукли, не создавайте несколько экземпляров Tk (). Вам также не нужно дважды импортировать tkinter.
import tkinter as tk
class split_screen(tk.Tk):
def __init__(self):
tk.Tk.__init__(self)
self.geometry("650x700")
self.configure(bg='black')
self.title("test")
left = tk.Frame(self, borderwidth=200, relief="solid")
right = tk.Frame(self, borderwidth=20, relief="solid")
box1 = tk.Frame(left, borderwidth=2, relief="solid")
box2 = tk.Frame(left, borderwidth=2, relief="solid")
box3 = tk.Frame(right, borderwidth=2, relief="solid")
label1 = tk.Label(box3, text="winner's" + "\n\n\n" + "Player 1",fg= "black", bg = "red", font = "david 18 bold underline")
label2 = tk.Label(box1, text="Computer 1",fg = "black", bg = "red", font= "david 18 bold underline")
label3 = tk.Label(box2, text="Computer 2",fg = "black", bg = "red", font= "david 18 bold underline")
clock1 = Clock(box1, 1000)
clock2 = Clock(box2, 2000)
clock3 = Clock(box3, 1300)
left.pack(side="left", expand=True, fill="both")
right.pack(side="right", expand=True, fill="both")
box3.pack(expand=True, fill="both", padx=10, pady=10)
box1.pack(expand=True, fill="both", padx=10, pady=10)
box2.pack(expand=True, fill="both", padx=10, pady=10)
label1.pack()
label2.pack()
label3.pack()
class Clock():
def __init__(self, frame, count):
self.frame = frame
self.label = tk.Label(frame, text="", width=10,fg="black", bg ="red", font="david 18 bold underline")
self.label.pack()
self.remaining = 0
self.countdown(count)
frame.configure(background="black")
def countdown(self, remaining = None):
if remaining is not None:
self.remaining = remaining
if self.remaining <= 0:
self.label.configure(text="time's up!")
else:
self.label.configure(text="%d" % self.remaining)
self.remaining = self.remaining - 1
self.frame.after(1000, self.countdown)
if __name__ == "__main__":
app = split_screen()
app.mainloop()
