how to download file from Google cloud storage using python

Question

I am working with Google Cloud Storage via Python, so wanted to know how to download the file via Python code. I know, a similar example is given in documentation but wanted to know the best way to authenticate via credentials.

Answer 1

Step 1: Install:

pip3 install google-cloud-storage
pip install --upgrade google-cloud-storage

Step 2: Followed by authenticating yourself using credentials(like project id, private key, private key_id, client email, and client id).

Step 3: From official documentation on Downloading objects:

def download_blob(bucket_name, source_blob_name, destination_file_name):
    """Downloads a blob."""

    storage_client = storage.Client()

    bucket = storage_client.bucket(bucket_name)
    blob = bucket.blob(source_blob_name)
    blob.download_to_filename(destination_file_name)

    print(
        "Blob {} downloaded to file path {}. successfully ".format(
            source_blob_name, destination_file_name
        )
    )
