scrape webpage after selecting from dropdown

Question

When going to https://www.comparis.ch/carfinder/default the "Modell" dropdown is inactive until you select something from the "Marke" dropdown. My goal is to scrape all "Modell" values by going through the list of all "Marke" values. As the URL does not change when selecting something from the "Marke" dropdown I am struggling to achieve this. A list of "Marke" values I can get easily with this code:

from bs4 import BeautifulSoup

newest_secondhand_cars = 'https://www.comparis.ch/carfinder/default'
newest_secondhand_cars = requests.get(newest_secondhand_cars)
newest_secondhand_cars = newest_secondhand_cars.content
soup = BeautifulSoup(newest_secondhand_cars, "lxml")

marken = [str(el).split('>')[1].split('<')[0] for el in list(soup.find('select', {'id': 'ddlMake'}).find_all('option'))][1:]

print(marken)

How can I now plug in the "Marke" values dynamically to then scrape alle the "Modell" values? This answer comes very close I think but I did not manage to get it done: scraping a response from a selected option in dropdown list. This would be the code trying to do a POST request with the "Marke" value and then scraping the "Modell" values from the response (which is not working):

from bs4 import BeautifulSoup
import requests

url = 'https://www.comparis.ch/carfinder/default'

with requests.Session() as session:
    session.headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36'}

    # parsing parameters
    response = session.get(url)
    soup = BeautifulSoup(response.content, 'lxml')

    data = {
        'MakeList': 'BMW',
        #'ctl00$ctl00$txtSearchWord': '',
        #'__EVENTTARGET': soup.find('input', {'name': '__EVENTTARGET'}).get('value', ''),
        #'__EVENTARGUMENT': soup.find('input', {'name': '__EVENTARGUMENT'}).get('value', ''),
        #'__LASTFOCUS': soup.find('input', {'name': '__LASTFOCUS'}).get('value', ''),
        #'__VIEWSTATE': soup.find('input', {'name': '__VIEWSTATE'}).get('value', ''),
        #'__VIEWSTATEGENERATOR': soup.find('input', {'name': '__VIEWSTATEGENERATOR'}).get('value', ''),
        #'__EVENTVALIDATION': soup.find('input', {'name': '__EVENTVALIDATION'}).get('value', ''),
    }

    # parsing data
    response = session.post(url, data=data)

    soup = BeautifulSoup(response.content, 'lxml')

    print(soup.find('select', {'id': 'ddlModelGroup'}))

import requests
from bs4 import BeautifulSoup
from itertools import zip_longest

r = requests.get("https://www.comparis.ch/carfinder/default")
soup = BeautifulSoup(r.text, 'html.parser')

marke = []
tag = []
model = []
for item in soup.findAll("select", {'id': 'ddlMake'}):
    for name in item.findAll("option")[1:]:
        marke.append(name.text)
for item in soup.findAll("select", {'id': 'ddlMake'}):
    for num in item.findAll("option")[1:]:
        tag.append(num.get("value"))
for a, b in zip_longest(marke, tag):
    print(f"{'*' * 10}Extracting: {a}{'*' * 10}
")
    r = requests.get(
        f"https://www.comparis.ch/carfinder/searchservice/GetModelGroupsForMake?makeID={b}").json()
    data = list(item['Value'].strip() for item in r)
    print(f"{data}
")
    model.append(data)

Output Sample:

**********Extracting: Aixam**********

['300', '325', '400', '500', '600', '721', '751', 'Crossline', 'MAC', 'Scouty']

And So On....

Or use the following:

import requests
from bs4 import BeautifulSoup
from itertools import zip_longest

r = requests.get("https://www.comparis.ch/carfinder/default")
soup = BeautifulSoup(r.text, 'html.parser')

marke = []
tag = []
model = []
for item in soup.findAll("select", {'id': 'ddlMake'}):
    for name in item.findAll("option")[1:]:
        marke.append(name.text)
for item in soup.findAll("select", {'id': 'ddlMake'}):
    for num in item.findAll("option")[1:]:
        tag.append(num.get("value"))
for a, b in zip_longest(marke, tag):
    print(f"Extracting: {a}")
    r = requests.get(
        f"https://www.comparis.ch/carfinder/searchservice/GetModelGroupsForMake?makeID={b}").json()
    data = list(item['Value'] for item in r)
    model.append(data)

for a, b in zip_longest(marke, model):
    print("Marke: {:<20}, Model: {:<100}".format(
        a, ", ".join(str(i).strip() for i in b)))
