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.

复制代码 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
