英文:
Convert list of key/value pairs to nested dictionary
问题
以下是您期望的输出所需的代码部分翻译：
from collections import defaultdict
data = [
['QR', ''],
['Cust', ''],
['fea', 'restroom'],
['chain', 'pa'],
['store', 'cd'],
['App', ''],
['End', 'EndnR'],
['Request', '0'],
['Sound', '15'],
['Target', '60'],
['Is', 'TRUE']
]
res = defaultdict(dict)
current_dict = res
for key, value in data:
if value == '':
current_dict = current_dict[key]
else:
current_dict[key] = value
print(dict(res))
这段代码将生成所需的嵌套字典结构，并输出期望的结果。
英文:
Input data:
data = [
['QR', ''],
['Cust', ''],
['fea', 'restroom'],
['chain', 'pa'],
['store', 'cd'],
['App', ''],
['End', 'EndnR'],
['Request', '0'],
['Sound', '15'],
['Target', '60'],
['Is', 'TRUE']
]
I want to turn this into a dictionary, and each blank value indicates the start of a new, nested sub-dictionary.
Desired output:
{
'QR': {
'Cust': {
'fea': 'restroom ',
'chain': 'pa',
'store': 'cd'
},
'App': {
'End': 'EndnR',
'Request': '0',
'Sound': '15',
'Target': '60',
'Is': 'true'
},
}
}
Here is my code so far:
from collections import defaultdict
res = defaultdict(dict)
for i in data:
res[i[0]] = i[1]
print(res)
But it only creates a flat dictionary with some blank values, not a nested dictionary.

得分: -1
以下是您要翻译的代码部分：
尝试这个：
result = {}
nbr_keys = 0
keys = [item[0] for item in data if item[1] == ""]
for index, item in enumerate(data):
if index == 0:
if item[1] == "":
key = item[0]
di[item[0]] = {}
else:
if item[1] == "":
di[key].update({item[0]: {}})
nbr_keys += 1
else:
di[key][keys[nbr_keys]].update({item[0]: item[1]})
这将输出：
{'QR': {'Cust': {'fea': 'restroom', 'chain': 'pa', 'store': 'cd'},
'App': {'End': 'EndnR',
'Request': '0',
'Sound': '15',
'Target': '60',
'Is': 'TRUE'}}}
英文:
try this:
result = {}
nbr_keys = 0
keys = [ item[0] for item in data if item[1] == "" ]
for index, item in enumerate(data):
if index == 0:
if item[1] == "":
key = item[0]
di[item[0]] = {}
else:
if item[1] == "":
di[key].update({item[0]: {}})
nbr_keys +=1
else:
di[key][keys[nbr_keys]].update({item[0]: item[1]})
which outputs this:
{'QR': {'Cust': {'fea': 'restroom', 'chain': 'pa', 'store': 'cd'},
'App': {'End': 'EndnR',
'Request': '0',
'Sound': '15',
'Target': '60',
'Is': 'TRUE'}}}
