How to generate UserLoginType[_token] for login request

问题

I'm trying to login into a website using a post request like this:

import requests

cookies = {
    '_SID': 'c1i73k2mg3sj0ugi5ql16c3sp7',
    'isCookieAllowed': 'true',
}

headers = {
    'Host': 'service.premiumsim.de',
    'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:56.0) Gecko/20100101 Firefox/56.0',
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
    'Accept-Language': 'en-US,en;q=0.5',
    'Referer': 'https://service.premiumsim.de/',
    'Content-Type': 'application/x-www-form-urlencoded',
    'DNT': '1',
    'Connection': 'keep-alive',
    'Upgrade-Insecure-Requests': '1',
}

data = [
  ('_SID', 'c1i73k2mg3sj0ugi5ql16c3sp7'),
  ('UserLoginType[alias]', 'username'),
  ('UserLoginType[password]', 'password'),
  ('UserLoginType[logindata]', ''),
  ('UserLoginType[_token]', '1af70f3d0e5b9e6c39e1475b6d84e9d125d076de'),
]

requests.post('https://service.premiumsim.de/public/login_check', headers=headers, cookies=cookies, data=data)

The problem is 'UserLoginType[_token] in params. The above code is working, but I don't have that token and have no clue how to generate it. So when I do my request, I do it without the _token and the request fails. Google did not found any helpful information about UserLoginType.

Does anyone know how to generate it(e.g. with another request first) to be able to login?

Edit: Thanks to the suggestion of t.m.adam I used bs4 to get the token:

import requests
from bs4 import BeautifulSoup as bs

tokenRequest = requests.get('https://service.premiumsim.de')
html_bytes = tokenRequest.text
soup = bs(html_bytes, 'lxml')
token = soup.find('input', {'id':'UserLoginType__token'})['value']
