How to sort the Python dict by key or value

如何对Python的字典类型进行排序，返回一个有序的数据？

对字典排序有一下几种方法：

sorted a dict by keys(Python2.4 or greater)

mydict = {
    '2014-02-03': ['item1', 'item2'],
    '2014-02-05': ['item2-1', 'item2-2']
}
for key in sorted(mydict.iterkeys()):
    print "%s: %s" % (key, mydict[key])

sorted by key(Python older than 2.4)

keylist = mydict.keys()
keylist.sort()
for key in keylist:
    print "%s: %s" % (key, mydict[key])

sorted a dict by value(Python2.4 or greater)

for k, v in sorted(mydict.iteritems(), key=lambda (k, v): (v, k)):
    print "%s: %s" % (k, v)

我需要对数据排序后，在模板中按照排的顺序显示出来：

solution:

result = []
for k in sorted(mydict.iterkeys()):
    result.append((k, mydict[k]))
    print "%s: %s" % (k, mydict[k])
