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
