[英]extract data from json file using python
I have this json file.我有这个 json 文件。
{
"entityId": "PROCESS_1234",
"displayName": "Windows System",
"firstSeenTms": 1619147697131,
"lastSeenTms": 1653317760000,
"properties": {
"detectedName": "Windows System",
"bitness": "32",
"metadata": [],
"awsNameTag": "Windows System",
"softwareTechnologies": [
{
"type": "WINDOWS_SYSTEM"
}
],
"processType": "WINDOWS_SYSTEM"
}
}
I need to extract entityId": "PROCESS_1234" and "properties": { "detectedName": "Windows System" as a data frame. The data frame needs to look like this:我需要提取 entityId": "PROCESS_1234" 和 "properties": { "detectedName": "Windows System" 作为数据框。数据框需要如下所示:
entityId detectedName
PROCESS_1234 Windows System
I have tried this:我试过这个:
print(resp2['entityId']['properties'][0]['detectedName'])
I get this error:我收到此错误:
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-6-09b87f04b95e> in <module>
----> 1 print(resp2['entityId']['properties'][0]['detectedName'])
TypeError: string indices must be integers
To extract entityId
, do:要提取entityId
,请执行以下操作:
print(resp2['entityId'])
To extract detectedName
, do:要提取detectedName
名称,请执行以下操作:
print(resp2['properties']['detectedName'])
this error occur when you pass a string value传递字符串值时会发生此错误
print(resp2[0][1]) try like this. print(resp2[0][1]) 试试这样。
The program该程序
import pandas as pd
data = {
"entityId": "PROCESS_1234",
"displayName": "Windows System",
"firstSeenTms": 1619147697131,
"lastSeenTms": 1653317760000,
"properties": {
"detectedName": "Windows System",
"bitness": "32",
"metadata": [],
"awsNameTag": "Windows System",
"softwareTechnologies": [
{
"type": "WINDOWS_SYSTEM"
}
],
"processType": "WINDOWS_SYSTEM"
}
}
rows = [(data['entityId'], data['properties']['detectedName'])]
x = pd.DataFrame(data=rows, columns=['entityId', 'detectedName'])
print(x)
The output输出
