如何製作True：兩個循環在python中同時運行

Question

基本上我需要同時運行兩個while循環。原因是我需要一個循環來更新GUI，另一個來檢查程序是否連接到互聯網。所以也許這需要多線程，或者我只是一個網頁去解決我的問題。這裏是我的源代碼：

# -*- coding: utf-8 -*- 

import sys 
import urllib2 
from Tkinter import * 
import time 
import socket 

def daMainProgram(): 

    airid = 'http://www.aviationweather.gov/metar/data?ids={airid}&format=raw&hours=0&taf=off&layout=off&date=0'.format(airid=e1.get()) 

    website = urllib2.urlopen(airid) 

    website_html = website.read() 

    data_start = website_html.find("<!-- Data starts here -->") 

    br1 = data_start + 25 

    br2 = website_html.find("<br />") 

    metar_slice = website_html[br1:br2] 

    print("Here is the undecoded METAR data:\n"+metar_slice) 

    root2 = Tk() 

    root2.title("#Conection_Made#") 

    metar_dat_label = Label(root2, text="Here is the undecoded METAR data:") 

    metar_dat_label_ln_2 = Label(root2, text=metar_slice) 

    metar_dat_label.grid(row=0) 

    metar_dat_label_ln_2.grid(row=1) 


def _quit(): 
    sys.exit() 

def internet(host="8.8.8.8", port=53, timeout=3): 
    try: 
     socket.setdefaulttimeout(timeout) 
     socket.socket(socket.AF_INET, socket.SOCK_STREAM).connect((host, port)) 
     return True 
    except Exception: 
     return False 
def tkupdate(): 
    while True: 
     root1.update() 

def internet_loop(): 
    while True: 
     out = internet() 
     if out == True: 
      connetion2internet.configure(text="YOU ARE CONNECTED TO THE INTERNET", fg="green") 
     if out == False: 
      connetion2internet.configure(text="YOU ARE NOT CONNECTED TO THE INTERNET", fg="red") 

root1 = Tk() 
root1.title("Welcome") 
warning = Label(root1, text="*********** WARNING REQURIES INTERET TO RUN ***********") 
warning.grid(row=0) 
connetion2internet = Label(root1, text="") 
connetion2internet.grid(row=1) 
airport_code = Label(root1,text="Enter Airport Code:") 
airport_code.grid(row=2, sticky="W") 
e1 = Entry(root1) 
e1.grid(row=2, sticky="E") 
button1 = Button(root1, text="Contunue", command=daMainProgram).grid(row=3, sticky="W") 
button2 = Button(root1, text="Quit", command=_quit) 
button2.grid(row=3, sticky="E") 

tkupdate() 
internet_loop()

如何處理下面的內容。產生兩個進程。每個人都可以並行運行，目標功能可以用自己的替換。

from multiprocessing import Process 
from time import sleep 

def func1(): 
    while True: 
     print("func1 up and running") 
     sleep(1) 

def func2(): 
    while True: 
     print("func2 up and running") 
     sleep(1) 


if __name__ == '__main__': 

    proc1 = Process(target=func1) 
    proc1.start() 

    proc2 = Process(target=func2) 
    proc2.start() 

輸出是：

func1 up and running 
func2 up and running 
func1 up and running 
func2 up and running 
func1 up and running 
func2 up and running 
func1 up and running 
func2 up and running 
...
