Is there any way of getting values from keys inside other keys?

Question

(first post sorry if i do this wrong) So I am making a bot (on discord) for me and my friends using discord.py (since python is the easiest code ever) and I've came across this. I need to get values from keys INSIDE OTHER keys. How do I do this?

So I've tried to change res to res.text and res.json and res.content and I could only find the "data" but not "id","name" or "description" which I need.

import discord
from discord.ext.commands import Bot
from discord.ext import commands
import requests, json
import asyncio

Client = discord.Client()
client = commands.Bot(command_prefix='?')
@client.event
async def on_ready():
    print('started')

@client.command()
async def findfriends(ctx,userid):
        res = requests.get("https://friends.roblox.com/v1/users/"+userid+"/friends")
        var = json.loads(res.text)
        def a(a):
                ID = a['id']
                return ID
        def b(b):
                Name = b['name']
                return Name
        def c(c):
                description = c['description']
                return description
        data = var['data'] #I can get this working
        print(data)
        #cv = data['name'] #but this wont work
        #id = a(var)       #nor this
        #name = b(var)     #nor this
        #desc = c(var)     #nor this
        #await ctx.send("\nID: " + id + "\nName: " + name + "\nDesc: " + desc) # this is just sending the message

client.run(BOT TOKEN HERE) #yes i did indeed add it but just for the question i removed it

As I said in the code, I can only get "data" working and not id,name or desc. For id name and desc it just throws an error

The https://friends.roblox.com/v1/users/<userid>/friends endpoint returns a list of all the friends that the user has, which can be of varying size.

With var = json.loads(res.text) you are loading the response text into a json object, which contains the key data , which you access using data = var['data'] . The new data variable now contains a list object, which is why cv = data['name'] fails to work as list objects do not take strings as keys, they are accessed using integers.

You need to iterate over the list to get all information on the friends. The below code goes through the list, pulls information for each item in the list and sends a message of the information once it has gone through all items.

import discord
from discord.ext.commands import Bot
from discord.ext import commands
import requests, json
import asyncio

client = commands.Bot(command_prefix='?')
@client.event
async def on_ready():
    print('started')

@client.command()
async def findfriends(ctx,userid):
    res = requests.get("https://friends.roblox.com/v1/users/"+userid+"/friends")
    var = json.loads(res.text)
    data = var['data']
    print(data)

    friends_msg = 'Friends information:'
    for friend in data:
        id = friend['id']
        name = friend['name']
        desc = friend['description']
        friends_msg = friends_msg + "\nID: " + id + "\nName: " + name + "\nDesc: " + desc

    await ctx.send(friends_msg)
