Python: Backslash from escaped single quote is being sent as part of JSON request

Unsure if title is an accurate way of phrasing question.

I have a JSON request and I’m passing in a variable "code". (It’s hardcoded here but it’s coming from another function)

code = ""date1.setValue('2023-01-01 00:00:00')""
data_string = f'{{"code": {code}}}'

    payload = {
        "id": "1",
        "inputs": [
            {
                "datatype": "BYTES",
                "data": [data_string],
            }
        ],
        ...
    }

The problem: in the request, the single quotes around the datetime is being escaped; but the backslash is showing up as part of request.
Is there a way to have that backslash not be there?

I did a normal print of the request:

{'id': '1', 'inputs': [{'datatype': 'BYTES', 'data': ['{{"code": "date1.setValue('2023-01-01 00:00:00')"']}]

The important part:

"code": "date1.setValue('2023-01-01 00:00:00')"

    This is expected since data is a list containing a single string, the string is printed sorrounded by single quotes: 'data': ['...'], so the single quotes included inside the string must be escaped.

    It appears that the problem is due to how the JSON data is structured. Single quotes within double-quoted strings in JSON do not need to be escaped in Python. Here’s way to make the payload without the extra backslashes:

    code = "date1.setValue('2023-01-01 00:00:00')"  # Removed unnecessary double quotes and backslashes

payload = {
    "id": "1",
    "inputs": [
        {
            "datatype": "BYTES",
            "data": [code],  # Just use the variable directly
        }
    ],
    # ...
}

    create a json_payload to convert a python object into a JSON string using json.dumps():

    import json

json_payload = json.dumps(payload)
