浅析Python中元祖、列表和字典的区别

#coding=UTF-8

#author:RXS002

animalslist = ['fox','tiger','rabbit','snake']

print('I do not like these',len(animalslist),'animals...')

 

for item in animalislist:

print(item)

 

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() #sort是排序

for i in range(0,len(animalslist)):

　　print(animallist[i])

I do not like these 4 animals...

fox tiger rabbit snake

操作后

pig rabbit snake tiger

>zoo = ('wolf','elephant','penguin')

>zoo.count('penguin')

>zoo.index('penguin')

>zoo.append('pig')

#coding = UTF-8 

#author:rxs002

dict1 = {'zhang':'张家辉'，'wang':'王宝强','li':'李冰冰','zhao':'赵薇'}

#字典的操作，添加，删除，打印

dict1['huang'] = '黄家驹'

del dict1['zhao']

for firstname,name in dict1.item():

　　print firstname,name　　

li 　　李冰冰

wang 王宝强

huang 黄家驹
