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?

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))
