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
