How can I use the term None instead of null in post request python project?

Question

In python, I had this variable:

v = None 

and this post request:

issue = {
                    "fields": 
                        {
                            "project": 
                            {
                                "id": 'x'
                            },
                            "summary": 's',
                            "issuetype": 
                            {
                                "name": 'n'
                            },
                            "components": 
                            [
                                {
                                "name": 'c1'
                                },
                                {
                                "name": v
                                },
                            ]
                         }

After debugging I got this error message:

'{"errorMessages":[],"errors":{"components":"Component name 'None' is not valid"}}'

The data is dynamic and that v as well, in case it is entered as a string then that won't be no issue at all but it if is empty in the entered data I want to skip in the post request then that will be an issue.

In postman I had no issue I add null to it and then it works.

It is just that in python where I cannot find a way to add that null. hence I tried None, 'null' and no way.

Isn't there any solution for this?

            #convert dict to string
            r = json.dumps(issue)
             
            #Replace None by null in the string
            r = r.replace("\"None\"", "null")
            
            #convert back the string to dict
            loaded_r = json.loads(r)

            response_post = requests.post(
            url_post,
            headers=headers , 
            json =  loaded_r 
            )
