单线程

•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 ''' i was listening to music.
