Equivalent JSONP for Python3

Question

I see a part of code on internet who use jsonp to make a request like this:

new Request.JSONP({
    url: "url",
    data: {
        params: JSON.encode({
            data: login
        })
    },
}).send()

And I would like ot know if it exist an equivalent of this jsonp in python. It's not a POST or GET method.

Thanks
