Download files from google drive with python - no API key

There are several scripts to download files from google drive using a shareable link. Some require
authentication others don't work. Here we're interested in those that do not require authentication.

The gdrivedl.py script provided by ndrplz just works fine.

> gdrivedl.py file_id

Another notable, currently non-working, alternative is googledrivedownloader. It probably worked at some point in time but today it fails. There's however a simple fix proposed in this thread. The code is here: 

import requests
 
def download_file_from_google_drive(id, destination):
    URL = "https://docs.google.com/uc?export=download"
 
    session = requests.Session()
 
    response = session.get(URL, params={"id": id, "confirm": 1}, stream=True)
    token = get_confirm_token(response)
 
    if token:
        params = {"id": id, "confirm": token}
        response = session.get(URL, params=params, stream=True)
 
    save_response_content(response, destination)
 
def get_confirm_token(response):
    for key, value in response.cookies.items():
        if key.startswith("download_warning"):
            return value
    return None
 
def save_response_content(response, destination):
    CHUNK_SIZE = 32768
 
    with open(destination, "wb") as f:
        for chunk in response.iter_content(CHUNK_SIZE):
            if chunk:  # filter out keep-alive new chunks
                f.write(chunk)
 
if __name__ == "__main__":
    file_id = "TAKE ID FROM SHAREABLE LINK"
    destination = "DESTINATION FILE ON YOUR DISK"
    download_file_from_google_drive(file_id, destination)
