標准庫（一）：collections之orderedDict

們自己寫的字典只能保存輸入的鍵值對，但是不能保存他們輸入的順序，這時候可以借助Python的標准庫collections里的orderedDict類 

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())
