Python体验(03)列表list和元组tuple

示例1：LIST

取得list长度len(list)，向list追加元素list.append()，list排序list.sort()，删除list元素 del list[index]

#!/usr/bin/python

#filename:list.py



#This is my shopping list

shoplist = ['apple','mango','carrot','banana']

print '\nI have',len(shoplist),'items to purchase:'

for item in shoplist:

        print item



print '\nAdd rice to the store: append()'

shoplist.append('rice')

print '\t ',shoplist



print '\nSORT the store: sort()\t'

shoplist.sort()

print '\t',shoplist



print '\nDEL item 0, the resule: del'

del shoplist[0]

print '\t',shoplist,'\n\n'

 示例2：tuple（元组）

列表中的列表不会丢失它的身份；可以认为列表中可存储列表，整个列表作为一个元素对待；可以索引到列表后再继续索引列表内的数据；注意最后通配符的用法： print '%s is %d years old' % (name, age)
print 'Why is %s playing with that python?' % name

#!/usr/bin/python

#filename:tuple.py



zoo = ['wolf','elephant','penguin']

new_zoo = ('monkey','dolphin',zoo)



print 'The OLD zoo had',len(zoo),'annimals:'

print '\t',zoo



print '\nThe NEW zoo have',len(new_zoo),'annimals:'

print '\t',new_zoo



print'\nAnimals brought from OLD zone are:',new_zoo[2] #zoo,the index is 2

print'Last animal brought from OLD zoo is: %s\n'%new_zoo[2][2]#zoo[2]



#--==------------ the output is  -----------------==--

#phoenix@debian:~/py$ python tuple.py

#The OLD zoo had 3 annimals:

#        ['wolf', 'elephant', 'penguin']



#The NEW zoo have 3 annimals:

#        ('monkey', 'dolphin', ['wolf', 'elephant', 'penguin'])



#Animals brought from OLD zone are: ['wolf', 'elephant', 'penguin']

#Last animal brought from OLD zoo is: penguin
