python把元组组合成字典

list=(("memory","","16g"),
      ("memory","","32g"),
      ("color","","red"),
      ("color","","blue"))

res={}
for info in list:
    if(res.has_key(info[0])):
        res[info[0]]["ids"].append(info[1])
        res[info[0]]["values"].append(info[2])
    else:
        item={"ids":[info[1]],"values":[info[2]]}
        res[info[0]]=item
print res
        

结果：

{'color': {'values': ['red', 'blue'], 'ids': ['', '']}, 'memory': {'values': ['16g', '32g'], 'ids': ['', '']}}
