需要在python中获取JSON特定键的所有值

Question

I am getting the following json data from pycurl in python. All I need to get those values into a list in python.

OUTPUT:
[{ 'name' : 'aaa', 'contact' : '123' },{ 'name' : 'bbb', 'contact' : '345' },{ 'name' : 'ccc', 'contact' : '555' }]

I need to get all those values of name key into a python list.

Answer 1

This is not a valid json data. Single quotes aren't allowed in JSON files. If that is the case, you need to first fix the JSON string.

import json

json_data_string = "[{ 'name' : 'aaa', 'contact' : '123' },{ 'name' : 'bbb', 'contact' : '345' },{ 'name' : 'ccc', 'contact' : '555' }]"
json_data_string = json_data_string.replace("'", "\"") #provided JSON content doesn't contains single quotes as part of values.

data = json.loads(json_data_string)
names = map(lambda datum: datum['name'], data)

Answer 2

jobtittles = list(map(lambda datum: datum['jobtitle'], jsonVal))

I used the above code in order to do something simila, jsonVal = JSON as string and ['jobtitle'] is the key in the JSON string, jobtitles is an array.

It worked wrapping the map() function with a list() function.
