python - 如何加入词典

Question

我有数据

stat=[{'state': {'europe': ['germany', 'england']}}, 
      {'state': {'europe': ['french', 'netherland']}},
      {'state': {'asian': ['japan', 'china']}}]

问题:列表之间如何加入？给定结果:

{'state': [{'europe': ['germany', 'england', 'french', 'netherland']}, 
           {'asian': ['japan', 'china']}]}

我正在使用 Python S60 和 Python 2.2

一个天真的尝试:

r={}
for d in stat:
    for k,v in d.iteritems():
        nd = r.setdefault(k,[])
        for tdk,tdv in v.iteritems():
            q = filter(lambda x: tdk in x.iterkeys(),nd)
            if not q:
                q = {tdk:[]}
                nd.append(q)
            else: q = q[0]
            q[tdk]+=tdv


print r
# prints {'state': [{'europe': ['germany', 'england', 'french', 'netherland']}, {'asian': ['japan', 'china']}]}
