序列使用enumerate（）的例子

#! /usr/bin/env python

#coding=utf-8

a=[1,2,3,4,5,6,7,8,9,10,11,12,13,14]

#每行显示6个列表元素
for i,v in enumerate(a):
    if i!=0 and i%6==0:
        print
    print v,

#列表中使用enumerate（）
print '*'*20+'List enumerate()'+'*'*20
a=[1,'abc',3,'I am a boy',2.34,-9]
for i,v in enumerate(a):
    print 'The %d element in list is:%s' %(i,v), \
     '  '*2+'Type:',type(v),'\n'#取得列表数据的类型,换行



#字符串中使用enumerate（）
print '*'*20+'String enumerate()'+'*'*20
b='1ab34cd'
for i,v in enumerate(b):
    print 'The %d element in list is:%s' %(i,v), \
     '  '*2+'Type:',type(v),'\n'#取得列表数据的类型,换行

#元组中使用enumerate（）
print '*'*20+'Tuple enumerate()'+'*'*20
c=(1,'abc',2.3,'5.6','I am a boy')

for i,v in enumerate(c):
    print 'The %d element in list is:%s' %(i,v), \

     '  '*2+'Type:',type(v),'\n'#取得列表数据的类型,换行

有一个list = ["a","b","c","d"],想要转化成一个dict = ["1":"a","2":"b","3":"c","4":"d"]

dict([str(i+1),j for i,j in enumerate(list)])
