Covert an HTTP POST with headers and body request to Python (Telerik Fiddle)

Question

I am using the following in Telerik Fiddler in order to create a POST request and it is successful:

POST https://login.random.com/connect/token HTTP/1.1 Connection: Keep-Alive Content-Type: application/x-www-form-urlencoded Accept: application/json Authorization: Basic XyXyXyXyXyXyXyXyXyXyXy= Content-Length: 105 Host: login.random.com

grant_type=password&username=xxx&password=xxxx&scope=random.api.external

and now I am trying to convert that into a Python script but it fails (returns error 400):

import json
import requests
import http.client

headers = {
    'Connection': 'Keep-Alive',
    'Content-Type': 'application/x-www-form-urlencoded',
    'Accept': 'application/json',
    'Authorization': 'Basic XyXyXyXyXyXyXyXyXyXyXy=',
    'Content-Length': '105',
    'Host': 'login.random.com'
}

body = {
  'grant_type': 'password',
  'username': 'xxx',
  'password': 'xxxx',
  'scope': 'random.api.external'
}


response = requests.post('https://login.random.com/connect/token', headers=headers, data=body)

I have also tried including all the above in the headers and it failed (error 400).

Am I missing a library maybe? The details are correct in my script.

I have found a solution to my problem. In Telerik Fiddler you can download a Code (Convert to Python) plugin and get an idea of how the final script should look like. After amending and testing, the final script is given below:

try:
    req = urllib.request.Request("https://login.random.com/connect/token")

    req.add_header("Connection", "Keep-Alive ")
    req.add_header("Content-Type", "application/x-www-form-urlencoded ")
    req.add_header("Accept", "application/json ")
    req.add_header("Authorization", "Basic XyXyXyXyXyXyXyXyXyXyXy= ")

    body = b"grant_type=password&username=xxx&password=xxxx&scope=random.api.external"

    response = urllib.request.urlopen(req, body)

except urllib.error.URLError as e:
    if not hasattr(e, "code"):
        print('False')
    response = e
except:
    print('False')

print('True')
