Example Usage: Listing Files in Google Drive

Let’s put your new Google API Python Client to the test with a simple example. This code snippet will list the first 10 files in your Google Drive. Before running this, make sure you have enabled the Google Drive API in the Google Cloud Console and have the necessary credentials set up.

from googleapiclient.discovery import build
from google.oauth2 import service_account

# Replace with the path to your service account key file
SERVICE_ACCOUNT_FILE = 'path/to/your/service_account.json'

# Replace with the scopes you need
SCOPES = ['https://www.googleapis.com/auth/drive.readonly']

creds = service_account.Credentials.from_service_account_file(
 SERVICE_ACCOUNT_FILE, scopes=SCOPES)

service = build('drive', 'v3', credentials=creds)

# Call the Drive v3 API
results = service.files().list(
 pageSize=10, fields="nextPageToken, files(id, name)").execute()
items = results.get('files', [])
if not items:
 print('No files found.')
else:
 print('Files:')
 for item in items:
 print(f"{item['name']} ({item['id']})")

Explanation:

1. Import Libraries: We import the necessary libraries from the google-api-python-client and google-auth.
2. Set Up Credentials: Replace 'path/to/your/service_account.json' with the actual path to your service account key file. Also, ensure the SCOPES list includes the necessary permissions for your task.
3. Build the Service: We build the Drive service using the credentials.
4. List Files: We call the files().list() method to retrieve a list of files, specifying the page size and the fields we want to retrieve (id and name).
5. Print Results: Finally, we iterate through the results and print the name and ID of each file.

Before running this script, make sure you have a service account set up in the Google Cloud Console and have downloaded the JSON key file. Also, enable the Google Drive API for your project. This example demonstrates how easy it is to use the Google API Python Client to interact with Google services.
