备忘一下python中的字典如何遍历,没有什么太多技术含量.仅供作为初学者的我参考.

#!/usr/bin/env python

# coding=utf-8

demoDict = {'1':'Chrome', '2':'Android'}

for key in demoDict.keys():

    print key
for value in demoDict.values():

    print value
for key in demoDict:

    print key, demoDict[key]


for key, value in demoDict.items():

    print key, value
for key in demoDict.iterkeys():

    print key
for value in demoDict.itervalues():

    print value
for key, value in demoDict.iteritems():

    print key, value
print 'dict.keys()=', demoDict.keys(), ';dict.iterkeys()=', demoDict.iterkeys()

interitems和iterms区别
