python dictionary items 未依序排列問題

import collections

s = {}
for i in range(0,36,2):
    s.update({i:str(i)*10})

sorted_s = collections.OrderedDict(sorted(s.items()))
print(s)
print('-------')
print(sorted_s)
print('=======')
for i, j in sorted_s.items():
    print('%s:%s' % (i,j))

將 dictionary s 重新排序後, 輸出次序就能正常囉~
