我需要一个 defaultdict 可以finaldict从第一个文件中获取给定的查询词列表。

最终的 dict 是两个文件中共享相同 ID 的一对单词的字典。例如foo, oof共享相同的1243ID 1453。是为了方便后面的词对搜索,当我尝试搜索时('foo','oof'),它会返回['1243','1453']。如果我在 finaldict 中搜索('foo','duh'),它不会返回任何内容,因为 wordpair 不共享任何相同的 ID。

query = ['foo','barbar']

finaldict = defaultdict(list)

finaldict = {('foo','oof'):['1243','1453']
('foo','rabrab'):['2323']
('barbar','duh'):['6452']}

我一直在这样做,但有没有更简单的方法来实现finaldict

query = ['foo','barbar']
from collections import defaultdict

dict1 = defaultdict(list)
dict2 = defaultdict(list)

dict1['foo'] = ['1234','1453','2323']; 
dict1['bar'] =['5230']; dict1['barbar'] =['6452']

dict2['1243']=['oof']
dict2['1453']=['oof']
dict2['4239']=['rba']
dict2['2323']=['rabrab']
dict2['6452']=['duh']

tt = defaultdict(defaultdict)
for p in sorted(query):
  for ss in sorted(dict1[p]):
    if len(dict2[ss]) != 0 and dict2[ss] != None:
      tt[p][ss] = dict2[ss]

finaldict = defaultdict(set)

for src in tt:
  for ss in tt[src]:
    for trg in tt[src][ss]:
      finaldict[(src, trg)].add(ss)

print finaldict[('foo','oof')]

上面的代码输出:

>>> print finaldict[('foo','oof')]
set(['1453'])
>>> for i in finaldict:
...     print i, finaldict[i]
... 
('foo', 'rabrab') set(['2323'])
('barbar', 'duh') set(['6452'])
('foo', 'oof') set(['1453'])

{(k1,v):k2 for k1 in dict1 for k2 in dict2 
           for v in dict2[k2] if k2 in dict1[k1]}

{('barbar', 'duh'): '6452', ('foo', 'oof'): '1453', ('foo', 'rabrab'): '2323'}
