Python解析JSON数组
Python解析JSON数组
提问于 2017-11-02 01:03:10
我正在试着组合一个小的python脚本，它可以从一个大的数据集中解析出数组。我希望从每个对象中提取一些key:values，以便稍后在脚本中回放它们。现在，我只想打印结果。我已经成功地在只包含对象的JSON文件中做到了这一点，但似乎不能让它在数组中工作。任何建议我们都将不胜感激。
下面是我的代码：
# Load up JSON Function
import json
# Open our JSON file and load it into python
input_file = open ('stores-small.json')
json_array = json.load(input_file)
# Create a variable that will take JSON and put it into a python dictionary
store_details = [
["name"],
["city"]
]
# Learn how to loop better =/
for stores in [item["store_details"] for item in json_array]
# Print my results
print(store_details)以下是示例JSON数据：
[
{
"id": 1000,
"type": "BigBox",
"name": "Mall of America",
"address": "340 W Market",
"address2": "",
"city": "Bloomington",

在您的for循环语句中，json_array中的每个item都是一个字典，并且字典没有键store_details。所以我稍微修改了一下程序
import json
input_file = open ('stores-small.json')
json_array = json.load(input_file)
store_list = []
for item in json_array:
store_details = {"name":None, "city":None}
store_details['name'] = item['name']
store_details['city'] = item['city']
store_list.append(store_details)
