下面小编就为大家带来一篇遍历python字典几种方法总结(推荐)。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧

如下所示：

									aDict = {'key1':'value1', 'key2':'value2', 'key3':'value3'}

									print '-----------dict-------------'

									for d in aDict:

									  print "%s:%s" %(d, aDict[d])

									print '-----------item-------------'

									for (k,v) in aDict.items():

									  print '%s:%s' %(k, v)

									#效率最高

									print '------------iteritems---------'

									for k,v in aDict.iteritems():

									  print '%s:%s' % (k, v)

									#最笨的方法

									print '---------iterkeys---------------'

									for k in aDict.iterkeys():

									  print '%s:%s' % (k, aDict[k])

									print '------------iterkeys, itervalues----------'

									for k,v in zip(aDict.iterkeys(), aDict.itervalues()):

									  print '%s:%s' % (k, v)

运行结果：

									<pre name="code" class="python">-----------dict-------------

									key3:value3

									key2:value2

									key1:value1

									-----------item-------------

									key3:value3

									key2:value2

									key1:value1

									------------iteritems---------

									key3:value3

									key2:value2

									key1:value1

									---------iterkeys---------------

									key3:value3

									key2:value2

									key1:value1

									------------iterkeys, itervalues----------

									key3:value3

									key2:value2

									key1:value1
