（1）需要执行python 程序如下：

#!/usr/bin/env pythonimport os,sysimport threadingfrom time import sleep,ctimeIpFileName='iplist.txt'shellFileName='shell.sh'iplist=[] class ThreadFunc(object):       def __init__(self,func,args,name=''):              self.name=name              self.func=func              self.args=args       def __call__(self):              self.res=self.func(*self.args)def loop(i,ip):    cmd='sh ' + shellFileName + ' ' + ip    os.system(cmd)def getIpList():    path=os.getcwd()    if os.path.isfile(path+'/'+IpFileName)==False:        print 'file ' + path+'/'+IpFileName + ' does not exist.'    fd=open(path+'/'+IpFileName)    content=fd.read().split('\n')    fd.close()    iplist=[]    for ip in content:        if ip!='':            iplist.append(ip)    return iplistdef main():       print 'starting at:',ctime()       threads=[]       iplist=getIpList()       nloops=xrange(len(iplist))       print iplist       for i in nloops:              t=threading.Thread(target=ThreadFunc(loop,(i,iplist[i]),loop.__name__))              threads.append(t)       for i in nloops:              threads[i].start()       for i in nloops:              threads[i].join()       print 'all done at:',ctime() if __name__=='__main__':       main()

（2）python 中需要处理的文本文件iplist如下：

[wln@localhost concurrence]$ cat iplist.txt 10.40.127.110.40.127.210.40.127.310.40.127.410.40.127.510.40.127.6

（3）python程序中调用的shell脚本内容如下：

[wln@localhost concurrence]$ cat shell.sh echo $1

（4）执行python 程序结果如下：

[wln@localhost concurrence]$ python 07.py starting at: Mon Jul  7 03:05:41 2014['10.40.127.1', '10.40.127.2', '10.40.127.3', '10.40.127.4', '10.40.127.5', '10.40.127.6']10.40.127.310.40.127.210.40.127.410.40.127.510.40.127.610.40.127.1all done at: Mon Jul  7 03:05:41 2014
