本身還是新手, 我用tkinter 做了兩個按鈕,Start和Stop
按了Start之後 會一直重覆從0數到9,
按了Stop之後, 會印出stop 但不會馬上停止, 需要完成一個loop之後才會停止
請問有什麼方法可以馬上停止
import tkinter as tk
import time
import threading
def k ():
global stop_var
stop_var = 0
while True:
if stop_var == 1:
break
for i in range(10):
print ( i)
time.sleep(0.5)
def run():
a = threading.Thread(target = k)
a.start()
def stop():
global stop_var
print ("stop")
stop_var = 1
window=tk.Tk()
buttonStart = tk.Button(window,width = 10, text = "Start", command = run)
buttonStop = tk.Button(window,width = 10, text = "Stop", command = stop)
buttonStart.pack()
buttonStop.pack()
window.mainloop()

多設幾個檢查點

That means you need to re-write your code.Doing a loop in another loop won't solve your issue.

if stop_var == 1 搬到 for 裡不就好了
