标题[问题] 如何立即停止执行绪
时间Sun Aug 16 12:07:16 2020
本身还是新手, 我用tkinter 做了两个按钮,Start和Stop
按了Start之後 会一直重覆从0数到9,
按了Stop之後, 会印出stop 但不会马上停止, 需要完成一个loop之後才会停止
请问有什麽方法可以马上停止
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()

4F：推 Falldog: if stop_var == 1 搬到 for 里不就好了 08/17 00:12
