[英]How to extract specific multiple values in JSON using python?
I Have to extract specific multiple values and print those specific values in a file if possible. 我必须提取特定的多个值,并在可能的情况下将这些特定的值打印在文件中。
I tried the below code to do this 我尝试下面的代码来做到这一点
JSON value from URL is:
{'data': [{'value': '0.0.0.0'}, {'value': '0.0.0.1'}, {'value': '0.0.0.2'}]}
import requests
import json
url = 'https://www.example.com'
response = requests.get('url', headers=headers , verify=False)
json_data = json.loads(response.text)
value = json_data['data'][0]['value']
print (value)
output of this : 0.0.0.0
But i want to print in a file(.txt) all these values like below: 但是我想在文件(.txt)中打印所有这些值,如下所示:
0.0.0.0
0.0.0.1
0.0.0.3
Please help me on this. 请帮我。
What you want is a loop 你想要的是一个循环
json_data = {'data': [{'value': '0.0.0.0'}, {'value': '0.0.0.1'}, {'value': '0.0.0.2'}]}
for x in json_data['data']:
print (x['value'])
To write the values to a file, expand @ergonaut's answer as here: 要将值写入文件,请按如下所示扩展@ergonaut的答案:
json_data = {'data': [{'value': '0.0.0.0'}, {'value': '0.0.0.1'}, {'value': '0.0.0.2'}]}
with open("test.txt", "w") as f:
for x in json_data['data']:
f.write(x['value'] + '\n')
Test the entries in test.txt
: 测试
test.txt
的条目:
with open("test.txt", "r") as f:
data = f.readlines()
for line in data:
print line.rstrip('\n')
Output: 0.0.0.0 0.0.0.1 0.0.0.2
输出:
0.0.0.0 0.0.0.1 0.0.0.2
