[nanjing3@master python]$ cat thread.py 
from time import sleep,ctime


def loop0():
    print 'start loop 0 at:',ctime()
    sleep(4)
    print 'loop 0 done at:',ctime()

def loop1():
    print 'start loop 1 at:',ctime()
    sleep(4)
    print 'loop 1 done at:',ctime()

def main():
    print 'starting  at:',ctime()
    loop0()
    loop1()
    print 'all DONE at:',ctime()

if __name__=='__main__':
    main()
