Python中元组,列表,字典的区别

#coding=utf-8
animalslist=['fox','tiger','rabbit','snake']
print "I don't like these",len(animalslist),'animals...'
for items in animalslist:
print items,
print "\n操作后"  
#对列表的操作,添加,删除，排序
animalslist.append('pig')
del animalslist[0]
animalslist.sort()
for i in range(0,len(animalslist)):
  print animalslist[i],

I don't like these 4 animals...
fox tiger rabbit snake

pig rabbit snake tiger

> zoo=('wolf','elephant','penguin')
> zoo.count('penguin')
1
> zoo.index('penguin')
2
> zoo.append('pig')
