当我按下按钮时，scan_open_ports开始工作，直到ip_list.curselection（）行停止为止，此行会阻止函数的运行... 我想知道为什么以及如何解决？ 谢谢
def scan_open_ports():
#long runtime function
print "Asdasd\"
ip_list.curselection()
def thr_open_ports():
threading.Thread(target=scan_open_ports).start()
ip_list = Listbox()
scan_ports = Button(window, text="Scan Open Ports", command= thr_open_ports, height = 10, width = 20)
答案 0 :(得分：0)
我从这个答案中偷偷窃了一些代码，以此作为一些tkinter代码的基础：How to align label, entry in tkinter
以下代码将其改编为具有Queue和Thread，它们仅在按下按钮后运行。
Thread通过mainloop与Queue通讯，而root.after()通过对from tkinter import *
from threading import Thread
from queue import Queue
from time import sleep
from random import randint
root = Tk()
root.geometry("583x591+468+158")
root.title("NOKIA _ANSI Performance")
root.configure(borderwidth="1")
root.configure(relief="sunken")
root.configure(background="#dbd8d7")
root.configure(cursor="arrow")
root.configure(highlightbackground="#d9d9d9")
root.configure(highlightcolor="black")
Label3 = Label(root)
Label3.configure(text='''Device IP Address :''')
Label3.pack()
Label5 = Label(root)
Label5.configure(text='''Username :''')
Label5.pack()
Entry5 = Entry(root)
Entry5.pack()
th = None
q = Queue()
def run_me(q):
sleep(5)
q.put(randint(1, 99))
def check_queue():
if not q.empty():
item = q.get()
Label5.configure(text=str(item))
root.after(200, check_queue)
def do_thread():
global th
th = Thread(target=run_me, args=(q,))
th.start()
Button1 = Button(root)
Button1.configure(pady="0")
Button1.configure(text='''NEXT''')
Button1.configure(command=do_thread)
Button1.pack()
root.after(200, check_queue)
mainloop()
的呼叫进行轮询
mainloop() Thread或check_queue()所做的轮询都未阻止sub_list = [[1,2,3],[4,5,5], [2,63,6]]
l1, l2, l3 = map(list, zip(*sub_list))
print(l1)
print(l2)
print(l3)
# Output
[1, 4, 2]
[2, 5, 63]
[3, 5, 6]
。
