How to find file id in python google drive folder?

Question

Python

I found a script for downloading files from google drive by id, but I don’t know how to find out the id of the file, knowing
the tk folder at the input I have only a folder

def download_G_file(G_file_id, G_file_name):
  #1o57TPQRQ8ps6tEhUHApEwBfTFlhk6YXq
  # качает файл с гугл диска
  from Google import Create_Service
  CLIENT_SECRET_FILE = 'client_secrets.json'
  API_NAME = 'drive'
  API_VERSION = 'v3'
  SCOPES = ['https://www.googleapis.com/auth/drive']
  file_ids = [G_file_id]
  file_names = [G_file_name]

  service = Create_Service(CLIENT_SECRET_FILE,API_NAME,API_VERSION, SCOPES)

  for file_id, file_name in zip(file_ids, file_names):
    request = service.files().get_media(fileId=file_id)

    fh = io.BytesIO()
    downloader = MediaIoBaseDownload(fd=fh, request=request)

    done = False	

    while not done:
      status, done = downloader.next_chunk()
      print('download progress {0}'.format(status.progress()*100))

    fh.seek(0)
    with open(os.path.join('D:\py\Raspisanie(project)', file_name), 'wb') as f:
      f.write(fh.read())
      f.close()

Everything turned out to be very simple
Krch something like this:
I need to find file_ids
(not my folder)
I put the Google module in a separate file, because it’s more convenient in my project

from Google import Create_Service
from docx_manage import file_redact
from google_auth_oauthlib.flow import Flow, InstalledAppFlow
from googleapiclient.discovery import build
from googleapiclient.http import MediaFileUpload, MediaIoBaseDownload
from google.auth.transport.requests import Request
#folder https://drive.google.com/drive/folders/1NNE2Up-wSW-m_0MIaRyzH-ee4VdLDcT3?usp=sharing
file_ids = []
CLIENT_SECRET_FILE = 'client_secrets.json'
API_NAME = 'drive'
API_VERSION = 'v3'
SCOPES = ['https://www.googleapis.com/auth/drive']
service = Create_Service(CLIENT_SECRET_FILE,API_NAME,API_VERSION, SCOPES)
par = "'1NNE2Up-wSW-m_0MIaRyzH-ee4VdLDcT3'" #id папки
Q = str( par +" in parents")
page_token = None
response = service.files().list(
q=Q,                                          
fields='nextPageToken, files(id, name, parents)',
pageToken=page_token).execute()
for file in response.get('files', []):
    # выведет все файла в папке
    print (file.get('name'), file.get('id'), file.get('parents'))
    file_ids.append(str(file.get('id')))
    print(file_ids)

Google.py module code

import pickle
import os
from google_auth_oauthlib.flow import Flow, InstalledAppFlow
from googleapiclient.discovery import build
from googleapiclient.http import MediaFileUpload, MediaIoBaseDownload
from google.auth.transport.requests import Request


def Create_Service(client_secret_file, api_name, api_version, *scopes):
    print(client_secret_file, api_name, api_version, scopes, sep='-')
    CLIENT_SECRET_FILE = client_secret_file
    API_SERVICE_NAME = api_name
    API_VERSION = api_version
    SCOPES = [scope for scope in scopes[0]]
    print(SCOPES)

    cred = None

    pickle_file = f'token_{API_SERVICE_NAME}_{API_VERSION}.pickle'
    # print(pickle_file)

    if os.path.exists(pickle_file):
        with open(pickle_file, 'rb') as token:
            cred = pickle.load(token)

    if not cred or not cred.valid:
        if cred and cred.expired and cred.refresh_token:
            cred.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRET_FILE, SCOPES)
            cred = flow.run_local_server()

        with open(pickle_file, 'wb') as token:
            pickle.dump(cred, token)

    try:
        service = build(API_SERVICE_NAME, API_VERSION, credentials=cred)
        print(API_SERVICE_NAME, 'service created successfully')
        return service
    except Exception as e:
        print('Unable to connect.')
        print(e)
        return None
