•单线程：在单线程中顺序执行两个循环。一定要一个循环结束之后，另一个才开始。总时间是各个循环运行时间之和。

#单线程时代：
#这里其实是2个进程，两者之间没有关联的2个进程，分别按照先后顺序在运行
from time import sleep,ctime

def music():
for i in range(2):
print 'i was listening to music. %s'%ctime()
sleep(1)

def move():
for i in range(2):
print 'i was at the movies! %s'%ctime()
sleep(5)

if __name__=='__main__':
music()#进程1
move()#进程2
print 'All over %s'%ctime()#输出为：Thu Nov 05 12:01:06 2015

#music()和move()更应该被看作是音乐和视频播放器,至于要播放什么歌曲和视频应该由我们使用时决定
#对上面的代码进行改造～～
