[英]How to extract these data items from JSON file?
I have a JSON file and I would like to get 'id' value and 'key' value for each champion:我有一个 JSON 文件,我想获取每个冠军的 'id' 值和 'key' 值:
Here example with 2 champions of my champion.json
file, but if I have 100 champions how can I do that?这里以我的
champion.json
文件的 2 个冠军为例,但如果我有 100 个冠军,我该怎么做?
{
"type": "champion",
"format": "standAloneComplex",
"version": "9.23.1",
"data": {
"Aatrox": {
"version": "9.23.1",
"id": "Aatrox",
"key": "266",
"name": "Aatrox",
"title": "the Darkin Blade"
},
"Ahri": {
"version": "9.23.1",
"id": "Ahri",
"key": "103",
"name": "Ahri",
"title": "the Nine-Tailed Fox"
}
}
}
My python file:我的 python 文件:
import json
all_data = open('champion.json', encoding="utf8")
data_champ = json.load(all_data)
for element in data_champ['data']:
print(data_champ[element]["key"])
print(data_champ[element]['id'])
In the structure of the JSON data in your question, the value associated with the data
key is a dictionary-of-dictionaries, so you would need to access the value of each one of them like this:在您的问题中 JSON 数据的结构中,与
data
键关联的值是一个字典字典,因此您需要像这样访问它们中的每一个的值:
import json
with open('champion.json', encoding="utf8") as all_data:
data_champ = json.load(all_data)
for value in data_champ['data'].values():
print(value["key"])
print(value['id'])
Output: Output:
266
Aatrox
103
Ahri
I also changed the file handling to ensure it gets closed properly by using a with
statement.我还更改了文件处理以确保使用
with
语句正确关闭它。
