英文:
Extract an element from json list array
问题
你想要的格式是这样的：
"subscriptions": [
{
"totalAmount": { "amount": "450.0" },
"tax": { "amount": "0.0" }
},
{
"totalAmount": { "amount": "25.0" },
"tax": { "amount": "0.0" }
}
]
你可以使用以下代码来实现这个目标：
new_dict = {}
for subscription in data[0]['client']['Outcome']['Options'][0]['subscriptions']:
new_subscription = {
'totalAmount': {'amount': subscription['totalAmount']['amount']},
'tax': {'amount': subscription['tax']['amount']}
}
new_dict.setdefault('subscriptions', []).append(new_subscription)
这段代码会循环遍历每个订阅，然后将它们的'totalAmount'和'tax'值提取到新的字典中，最后将这些字典组成一个新的'subscriptions'列表。
英文:
[
{
"confirmed": false,
"client": {
"Outcome": {
"ResponseId": "64352036ead00dc1fd8d",
"Options": [
{
"optionState": "AUTHORISED",
"Endorsements": [
{
"PointId": "7e8fb6e0-0435-45c3-b2a5-82cb2074bf63",
"LifetimeIds": ["00002"],
"Code": "001",
"Name": "Name of the provider",
"Wording": "Wording goes here",
"Variables": [{ "name": "${value}", "value": "450" }]
}
],
"subscriptions": [
{
"totalAmount": { "amount": "450.0", "currencyCode": "EUR" },
"tax": { "amount": "0.0", "currencyCode": "EUR" },
"subscription": { "amount": "450.0", "currencyCode": "EUR" },
"code": "Movie",
"message": "You have access to all movies in the library"
},
{
"totalAmount": { "amount": "25.0", "currencyCode": "EUR" },
"tax": { "amount": "0.0", "currencyCode": "EUR" },
"subscription": { "amount": "25.0", "currencyCode": "EUR" },
"code": "Library",
"message": "You are able to borrow books"
}
]
}
]
}
},
"startDate": "17-04-2023",
"name": "Joe Blogg",
"email": "joe@blogg.com",
"phoneNumber": "01234567890"
}
]
I wounder if someone can help me, I'm trying to loop through 'subscriptions' element and print out only the ['tax']['amout'] and ['totalAmount']['amount'] - adding them into a dictionary. But I'm getting an error message that '
list indices must be integers or slices, not str
so I'm looking to have a new dictionary that has this format:
"subscriptions": [
{
"totalAmount": { "amount": "450.0" },
"tax": { "amount": "0.0"}
},
{
"totalAmount": { "amount": "25.0"},
"tax": { "amount": "0.0"}
}
]
new_dict = {}
for i in data['client']['Outcome']['Options']['subscriptions']:
new_dict.update({'totalAmount': i['totalAmount']['amount']})
new_dict.update({'tax': i['tax']['amount']})
The code about is what I was trying to use to parse it, but It's giving me error - so I can't build a new dictionary with the values that I'm interested in.
Any help would be appreciated.

Here is the translated code:
如果您每个列表只有一条记录，您可以使用：
new_dict = {'subscriptions': []}
# 这里 --v 这里 --v
for subscription in data[0]['client']['Outcome']['Options'][0]['subscriptions']:
new_dict['subscriptions'].append({'totalAmount': {'amount': subscription['totalAmount']['amount']},
'tax': {'amount': subscription['tax']['amount']}})
输出：
>>> json.dumps(new_dict, indent=4)
{
"subscriptions": [
{
"totalAmount": {
"amount": "450.0"
},
"tax": {
"amount": "0.0"
}
},
{
"totalAmount": {
"amount": "25.0"
},
"tax": {
"amount": "0.0"
}
}
]
}
(Note: I've replaced the HTML entities like " with their corresponding characters in the translated code.)
英文:
If you have only one record per list, you can use:
new_dict = {'subscriptions': []}
# HERE --v HERE --v
for subscription in data[0]['client']['Outcome']['Options'][0]['subscriptions']:
new_dict['subscriptions'].append({'totalAmount': {'amount': subscription['totalAmount']['amount']},
'tax': {'amount': subscription['tax']['amount']}})
Output:
>>> json.dumps(new_dict, indent=4)
{
"subscriptions": [
{
"totalAmount": {
"amount": "450.0"
},
"tax": {
"amount": "0.0"
}
},
{
"totalAmount": {
"amount": "25.0"
},
"tax": {
"amount": "0.0"
}
}
]
}
