标准库（一）：collections之orderedDict

们自己写的字典只能保存输入的键值对，但是不能保存他们输入的顺序，这时候可以借助Python的标准库collections里的orderedDict类 

from collections import OrderedDict
my_ordered_diction = OrderedDict()
my_ordered_diction['wukong'] = 'C++'
my_ordered_diction['bajie'] = 'Java'
my_ordered_diction['shaseng'] = 'Qt'
my_ordered_diction['tangsheng'] = 'python'

for name,laugage in my_ordered_diction.items():
    print(name.title() + ' favorite laugage is ' + laugage.title())
