Question

python thread 线程里面os.system 怎么挂掉

Answer 1

Python用sleep停止一个线程的运行，而不影响主线程的运行，案例代码如下：
from threading import *
import time

class MyThread(Thread):
def run (self):
self.ifdo = True;
while self.ifdo:
print 'I am running...'
time.sleep(2)

def stop (self):
print 'I am stopping it...'
self.ifdo = False;

tr = MyThread()
tr.setDaemon(True)
tr.start()
print 'I will stop it...'
time.sleep(5)
tr.stop()
tr.join()
