Add variable value in a JSON string in Python

Question

I am puzzled why this is not working. I am trying add my variable value in the JSON and everytime I add it, it is not showing properly in my JSON string.

hostname = "machineA.host.com"

I need to add the above hostname information to the below JSON document -

b"{\"Machine Name\":\"\"+hostname+\"\"}", None, True)

But whenever I am adding it in the above way, it is not working at all.

Not sure what wrong I am doing here?

Answer 1

instead of manipulating the string consider having the data as a python structure and then dump it to json

>>> d = {}
>>> d['Machine Name'] = hostname
>>> json.dumps(d)
'{"Machine Name": "machineA.host.com"}'

Answer 2

Please see this example you will get some idea.

test=f"Your order total is $ 150."

{"Total":"'+test+'"}
