json.dumps to keep dictionary keys

[batchenr]

Hello,
im using python3 on ubuntu 18 machine
i am new to python

i have this script :

import json
import psutil
d = {}

mem = psutil.virtual_memory()
dmem = mem._asdict()
print(json.dumps(dmem))

and i get this result :

["total": 4416118784, "available": 3831390208, "percent": 13.2]]

and so on..

i want to make an order here because im going to add

psutil.swap_memory()
psutil.cpu_times()
psutil.cpu_percent(interval=1, percpu=True)

so the qustions are :

if i want to make an order in the response like this :

result = {
        'RAM' : mem
         }

print(json.dumps(result))

i get the results without the keys :

["RAM": [4416118784, 3831066624, 13]

How can i keep the keys so it will look like this :

["RAM": [total : 4416118784, available : 3831066624, precent : 13]

thanks
