python多线程实现同时执行两个while循环的操作

from time import sleep, ctime

def muisc(func):
  while True:
    print 'Start playing： %s! %s' %(func,ctime())
    sleep(2)

def player(name):

  if r == 'mp3':
    muisc(name)
  else:
    if r == 'mp4':
      move(name)
    else:
      print 'error: The format is not recognized!'

list = ['爱情买卖.mp3','阿凡达.mp4']

threads = []
files = range(len(list))

#创建线程
for i in files:
  t = threading.Thread(target=player,args=(list[i],))
  threads.append(t)

if __name__ == '__main__':
  #启动线程
  for i in files:
    threads[i].start()
  for i in files:
    threads[i].join()

  #主线程
  print 'end:%s' %ctime()

>>> list1 = ['a', 'b', 'c', 'd']
>>> list2 = ['apple', 'boy', 'cat', 'dog']
>>> for x, y in zip(list1, list2):
  　　print(x, 'is', y)

# 输出
a is apple
b is boy
c is cat
d is dog
