Python中的字典遍历备忘

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
