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.
代码如下:
#!/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区别
