[英]How to combines all the values for same key of JSON data using Python
[英]Python: sum all the values with same key in json?
我讀了一個 Json 文件。 我想打印“total_signatures”的總和。
{
"response": [
{
"domains": [],
"total_network_connections": 0,
"total_processes": 0,
"total_signatures": 0,
},
{
"analysis_start_time": "2018-03-05 08:54:07",
"avdetect": 52,
"certificates": [],
"classification_tags": [],
"domains": [],
"total_signatures": 55,
"type": "PE32 executable (GUI) Intel 80386, for MS Windows",
"type_short": [
"peexe",
"executable"
],
"verdict": "malicious",
"vxfamily": "Trojan.Agent"
},
{
"analysis_start_time": "2016-05-18 09:10:50",
"avdetect": 52,
"certificates": [],
"classification_tags": [],
"total_signatures": 35,
..............
我試過這個但沒有用 ---> AttributeError: 'list' object has no attribute 'values'
a = sum(d['total_signatures'] for d in data['response'].values() if d)
我該如何解決這個問題? 謝謝
這應該做:
In [48]: d
Out[48]:
{'response': [{'domains': [],
'total_network_connections': 0,
'total_processes': 0,
'total_signatures': 0},
{'analysis_start_time': '2018-03-05 08:54:07',
'avdetect': 52,
'certificates': [],
'classification_tags': [],
'domains': [],
'total_signatures': 55,
'type': 'PE32 executable (GUI) Intel 80386, for MS Windows',
'type_short': ['peexe', 'executable'],
'verdict': 'malicious',
'vxfamily': 'Trojan.Agent'},
{'analysis_start_time': '2016-05-18 09:10:50',
'avdetect': 52,
'certificates': [],
'classification_tags': [],
'total_signatures': 35}]}
In [49]: sum([x['total_signatures'] for x in d['response']])
Out[49]: 90
試試這個
json = {...}
sum = 0
for i in json['response']:
sum += (i['total_signatures'])
print(sum)
出去:
90
