试图获得直系子女,但让所有子女都使用BeautifulSoup

I am trying to get create a dictionary of categories especially a food from this url. Now, when I am trying to use the below code, it is giving repetitive li items.

from bs4 import BeautifulSoup as bs
import requests

url = 'https://developer.foursquare.com/docs/build-with-foursquare/categories/'
req = requests.get(url)
soup = bs(req.text)

food_categories = soup.select('div.documentTemplate__Content-sc-5mpekp-0 > ul > li:nth-child(4)')[0]

for tagli in food_categories.find_all("li"):
    print(tagli.find('h3').text)
    for another_tagli in tagli.find_all('ul'):
        for some_tagli in another_tagli.find_all('li'):
            print(some_tagli.find('h3').text)
            for one_tagli in some_tagli.find_all('ul'):
                for aon_tagli in one_tagli.find_all('li'):
                    print(aon_tagli.find('h3').text)

Now, as per many stackoverflow posts, I have tried to use recursive=False argument to get the only direct children, but if I use that I get nothing.

我正在寻找这样的输出:

{
  'food': {
    'Afghan Restaurant': [],
    'African Restaurant': ['Ethiopian Restaurant'],
    'Asian Restaurant': {
      'Chinese Restaurant': ['Anhui Restaurant', 'Beijing Restaurant']
    }
  }
}

请在这里指导我。
