python 3从json字典中获取特定值

Question

I have a dictionary I'm getting from an API call. I am trying to grab a specific value from the results.

names = requests.get("http://some.api")

The result of that call when printed looks like this

{'mynames': [{'id': 38, 'name': 'Betsy'}, {'id': 93, 'name': 'Pitbull'}, {'id': 84, 'name': 'Liberty'}]}

I've tried the code below just to grab the result with 'Pitbull' as its name

filtered_names = {k:v for (k,v) in names.items() if "Pitbull" in v}

I get an error of

AttributeError: 'Response' object has no attribute 'items'

How can I just grab a specific value from the data that is being pulled from the API call?

Answer 1

requests.get gives a 'Response' object rather than a dict . Only the latter has an items method for iteration.

You can use the json library to retrieve a regular Python dictionary:

import json
import requests

names = requests.get("http://some.api")
d = json.loads(names.text)

Then note you have a dictionary with one key where the value is a list of dictionaries. So you need to access d['mynames'] to retrieve in-scope dictionaries via a list comprehension.

filtered_names = [el for el in d['mynames'] if 'Pitbull' in el['name']]

# [{'id': 93, 'name': 'Pitbull'}]

Answer 2

import json
names = requests.get('https://api')
Json = json.loads(names)

filtered_names = {k:v for k,v in Json.items() if "Pitbull" in v}

Now one question in our mind must come what does this json.py do? Well for Answer to this question you can refer enter link description here

Hope this doesn't throw AttributeError
