Threading in Python, Please check the script

[Robert Clove]

Hi All,

I have made a script in which i have started two thread named thread 1 and
thread 2.
In thread 1 one function will run named func1 and in thread 2 function 2
will run named func 2.
Thread 1 will execute a command and wait for 60 seconds.
Thread 2 will run only till thread 1 is running .
Again after that the same process continues in while after a break of 80
Seconds.

I am a beginner in python.
Please suggest what all i have done wrong and how to correct it.


#!/usr/bin/python

import threading
import time
import subprocess
import datetime
import os
import thread

thread.start_new_thread( print_time, (None, None))
thread.start_new_thread( print_time1, (None, None))
command= "strace -o /root/Desktop/a.txt -c ./server"
final_dir = "/root/Desktop"
exitflag = 0
# Define a function for the thread
def print_time(*args):
    os.chdir(final_dir)
    print "IN first thread"
    proc = subprocess.Popen(command,shell=True,stdout=subprocess.PIPE,
stderr=subprocess.PIPE)
    proc.wait(70)
    exitflag=1

def print_time1(*args):
    print "In second thread"
    global exitflag
    while exitflag:
        thread.exit()
        #proc =
subprocess.Popen(command1,shell=True,stdout=subprocess.PIPE,
sterr=subprocess.PIPE)



# Create two threads as follows
try:
    while (1):
        t1=threading.Thread(target=print_time)
        t1.start()
        t2=threading.Thread(target=print_time1)
        t2=start()
        time.sleep(80)
        z = t1.isAlive()
        z1 = t2.isAlive()
        if z:
            z.exit()
        if z1:
            z1.exit()
           threading.Thread(target=print_time1).start()
           threading.Thread(target=print_time1).start()
        print "In try"
except:
   print "Error: unable to start thread"
