給予名單上有字典清單如下圖所示:如何使字典從字典
targer = [
{"id":1,"search":"xyz"},
{"id":2,"children":[
{"id":3,"search":'xyz'},
{"id":4,"search":'xyz'},
{"id":5,"children":[
{"id":6,"search":'xyz'},
{"id":7,"search":'xyz'},
{"id":8,"search":'xyz'}]},
{"id":9,"search":'xyz'},
{"id":10,"search":'xyz'}]},
{"id":11},{"id":12}]
現在我要讓詞典列表如下圖所示,從目標列表:
output = [
{'tier1': 1, 'searchterm': 'xyz'},
{'tier1': 2, 'tier2': 3,'searchterm': 'xyz'},
{'tier1': 2,'tier2': 4,'searchterm': 'xyz'},
{'tier1': 2, 'tier2': 5,'tier3': 6,'searchterm': 'xyz'},
{'tier1': 2, 'tier2': 5,'tier3': 7,'searchterm': 'xyz'},
{'tier1': 2, 'tier2': 5,'tier3': 8, 'searchterm': 'xyz'},
{'tier1': 2, 'tier2': 9,'searchterm': 'xyz'},
{'tier1': 2, 'tier2': 10,'searchterm': 'xyz'},
{'tier1': 11, 'searchterm': 'xyz'},
{'tier1': 12, 'searchterm': 'xyz'}]
我嘗試了一些步驟: 1.首先我在轉變目標列表中列出如下圖所示:
mylist = [
[1, 'xyz'],
[2, 3, 'xyz'],
[2, 4, 'xyz'],
[2, 5, 6, 'xyz'],
[2, 5, 7, 'xyz'],
[2, 5, 8, 'xyz'],
[2, 9, 'xyz'],
[2, 10, 'xyz'],
[11],
[12]]
2.然後我採用下面的代碼上MYLIST得到輸出:
for i in lis:
dic={}
length=len(i)
if length==2:
dic['tier1']=i[0]
dic['searchterm']=i[1]
if length==3:
dic['tier1']=i[0]
dic['tier2']=i[1]
dic['searchterm']=i[2]
if length==4:
dic['tier1']=i[0]
dic['tier2']=i[1]
dic['tier3']=i[2]
dic['searchterm']=i[3]
if length==5:
dic['tier1']=i[0]
dic['tier2']=i[1]
dic['tier3']=i[2]
dic['tier4']=i[3]
dic['searchterm']=i[4]
if length==6:
dic['tier1']=i[0]
dic['tier2']=i[1]
dic['tier3']=i[2]
dic['tier4']=i[3]
dic['tier5']=i[4]
dic['searchterm']=i[5]
target.append(dic)
但我想從出應用上面的步驟直接目標列表輸出。 請幫忙解決這個問題。

爲什麼是'等級1的'searchterm'值:11'和'等級1:12' 「XYZ」?在原始數據結構中,這些字典沒有「搜索」鍵。 – 2013-03-18 21:05:17
