Prerequisites
To follow along with this guide, please make sure to have:
created a service account and downloaded the private key (JSON file) for authentication (please check out my detailed guide)
installed the Python client library for Google Cloud Storage:
pip install --upgrade google-cloud-storage
Checking if a file exists on Google Cloud Storage
To check if a file exists in Google Cloud Storage using Python, use the Blob.exists() method which returns a Boolean:
from google.cloud import storage
# Authenticate ourselves using the private key of our service accountpath_to_private_key = './gcs-project-354207-099ef6796af6.json'client = storage.Client.from_service_account_json(json_credentials_path=path_to_private_key)
bucket = storage.Bucket(client, 'example-bucket-skytowner')blob = bucket.blob('cat.png')blob.exists()
True
Here, note the following:
gcs-project-354207-099ef6796af6.jsonis the name of the credential JSON file for the service account. This file is located in the same directory as this Python script.we are checking whether the file
cat.pngexists - and yes, it does!
