Getting <response[200]> with Python http requests instead of INT

r = requests.post('https://www.9kw.eu/index.cgi', data = udajepost)

Here, r is the whole response object which has many attributes. I guess, you only need r.text. So, you can just use:

print(r.text) 

You're looking for the response of the request:

print(r.text)

In this way you'll have the plain text response.
