Answer 1

You can install https://pypi.org/project/googleDriveFileDownloader/

pip install googleDriveFileDownloader

And download the file, here is the sample code to download

from googleDriveFileDownloader import googleDriveFileDownloader
a = googleDriveFileDownloader()
a.downloadFile("https://drive.google.com/uc?id=1O4x8rwGJAh8gRo8sjm0kuKFf6vCEm93G&export=download")

Here's an easy way to do it with no third-party libraries and a service account.

pip install google-api-core and google-api-python-client

from googleapiclient.discovery import build
from googleapiclient.http import MediaIoBaseDownload
from google.oauth2 import service_account
import io

credz = {} #put json credentials her from service account or the like
# More info: https://cloud.google.com/docs/authentication

credentials = service_account.Credentials.from_service_account_info(credz)
drive_service = build('drive', 'v3', credentials=credentials)

file_id = '0BwwA4oUTeiV1UVNwOHItT0xfa2M'
request = drive_service.files().get_media(fileId=file_id)
#fh = io.BytesIO() # this can be used to keep in memory
fh = io.FileIO('file.tar.gz', 'wb') # this can be used to write to disk
downloader = MediaIoBaseDownload(fh, request)
done = False
while done is False:
    status, done = downloader.next_chunk()
    print("Download %d%%." % int(status.progress() * 100))

I recommend gdown package:

import gdown

url = 'https://drive.google.com/uc?id=0B9P1L--7Wd2vU3VUVlFnbTgtS2c'
output = 'spam.txt'
gdown.download(url, output, quiet=False) 

Answer 4

This has also been described above,

   from pydrive.auth import GoogleAuth
   gauth = GoogleAuth()
   gauth.LocalWebserverAuth()
   drive = GoogleDrive(gauth)

This creates its own server too do the dirty work of authenticating

   file_obj = drive.CreateFile({'id': '<Put the file ID here>'})
   file_obj.GetContentFile('Demo.txt') 

This downloads the file

Answer 5

Generally speaking, a URL from a shared file from Google Drive looks like this

https://drive.google.com/file/d/1HV6vf8pB-EYnjcJcH65eGZVMa2v2tcMh/view?usp=sharing

where 1HV6vf8pB-EYnjcJcH65eGZVMa2v2tcMh corresponds to fileID.

Hence, you can simply create a function to get the fileID from the URL, like this where url = https://drive.google.com/file/d/1HV6vf8pB-EYnjcJcH65eGZVMa2v2tcMh/view?usp=sharing,

def url_to_id(url):
    x = url.split("/")
    return x[5]

Printing x will give

['https:', '', 'drive.google.com', 'file', 'd', '1HV6vf8pB-EYnjcJcH65eGZVMa2v2tcMh', 'view?usp=sharing']

And so, as we want to return the 6th array value, we use x[5].

Answer 6

PyDrive allows you to download a file with the function GetContentFile(). You can find the function's documentation here.

See example below:

# Initialize GoogleDriveFile instance with file id.
file_obj = drive.CreateFile({'id': '<your file ID here>'})
file_obj.GetContentFile('cats.png') # Download file as 'cats.png'.

This code assumes that you have an authenticated drive object, the docs on this can be found here and here.

In the general case this is done like so:

from pydrive.auth import GoogleAuth

gauth = GoogleAuth()
# Create local webserver which automatically handles authentication.
gauth.LocalWebserverAuth()

# Create GoogleDrive instance with authenticated GoogleAuth instance.
drive = GoogleDrive(gauth)

Info on silent authentication on a server can be found here and involves writing a settings.yaml (example: here) in which you save the authentication details.
