如何根据价值命令假肢?
原标题:How to order a Dictionary based on the value?

我有象牙齿一样的理论家。

tel = { jack : 18,  sape : 4139,  sar : 2139,  mape : 319,  sipe : 29}

我想根据 like令的价值下令这样做。

tel = { sape : 4139,  sar : 2139,  mape : 319,  sipe : 29  jack : 18}

我搜索了这个网站,并发现了无关的结果。 是否有任何内在功能?

问题回答

不能订购<条码>。 要么使用定购物,要么采用其他顺序。

sorted(tel.iteritems(), key=operator.itemgetter(1), reverse=True)

在2.7或3.1年级,你可以使用命令分局:

from collections import OrderedDict
from operator import itemgetter
tel = { jack : 18,  sape : 4139,  sar : 2139,  mape : 319,  sipe : 29}
newtel = OrderedDict(sorted(tel.items(), key=itemgetter(1), reverse=True))

EDIT:现在使用物品而不是手提,请护理人员。 向那些认为更清楚老的方法的人道歉。

import operator
sorted(my_dict.iteritems(), key=operator.itemgetter(1))
