備忘一下python中的字典如何遍歷,沒有什么太多技術含量.僅供作為初學者的我參考.

代碼如下:
#!/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區別
