How do I format a list of numbers for JSON API payload?

Question

I need to post some JSON to a REST API. I want the payload to look like this:

{"id": {2342,2354,5676,7423}}

The numbers need to come from a list:

userid = [2342,2354,5676,7423]

I tried to loop through the list using something like this:

payload = {"id": {",".join([str(i) for i in userid])}}

But that gives me a quote around all the numbers which then fails:

{'id': {'2342,2354,5676,7423'}}

How can I insert those numbers into JSON without the quotes?

Thanks!

Answer 1

It is impossible. {"id": {2342,2354,5676,7423}} is not a valid JSON format. You can verify the validity of a JSON object using the function json.dumps from the json package.

Answer 2

here's how :

payload = {2342,2354,5676,7423}
x = {"id": payload}

to have this:

{"id": {2342,2354,5676,7423}}

but this is not a valid JSON format

do you mean

payload = {"id": row} 

to have something like this

{'id': [2342, 2354, 5676, 7423]}
