Python中的字典遍歷備忘

    備忘一下python中的字典如何遍歷,沒有什么太多技術(shù)含量.僅供作為初學(xué)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()
