S3Path provide a Python convenient File-System/Path like interface for AWS S3 Service using boto3 S3 resource as a driver.
Like pathlib, but for S3 Buckets
AWS S3 is among the most popular cloud storage solutions. It's object storage, is built to store and retrieve various amounts of data from anywhere.
Currently, Python developers use Boto3 as the default API to connect / put / get / list / delete files from S3.
S3Path blends Boto3's ease of use and the familiarity of pathlib api.
From PyPI:
.. code:: bash
$ pip install s3path
From Conda:
.. code:: bash
$ conda install -c conda-forge s3path
The following example assumes an s3 bucket setup as specified bellow:
.. code:: bash
$ aws s3 ls s3://pypi-proxy/

Importing the main class:
.. code:: python
from s3path import S3Path
Listing "subdirectories" - s3 keys can be split like file-system with a / in s3path we:
.. code:: python
bucket_path = S3Path('/pypi-proxy/') [path for path in bucket_path.iterdir() if path.is_dir()] [S3Path('/pypi-proxy/requests/'), S3Path('/pypi-proxy/boto3/'), S3Path('/pypi-proxy/botocore/')]
Listing html source files in this "directory" tree:
.. code:: python
bucket_path = S3Path('/pypi-proxy/') list(bucket_path.glob('**/*.html')) [S3Path('/pypi-proxy/requests/index.html'), S3Path('/pypi-proxy/boto3/index.html'), S3Path('/pypi-proxy/botocore/index.html')]
Navigating inside a "directory" tree:
.. code:: python
bucket_path = S3Path('/pypi-proxy/') boto3_package_path = bucket_path / 'boto3' / 'boto3-1.4.1.tar.gz' boto3_package_path S3Path('/pypi-proxy/boto3/boto3-1.4.1.tar.gz')
Querying path properties:
.. code:: python
boto3_package_path = S3Path('/pypi-proxy/boto3/boto3-1.4.1.tar.gz') boto3_package_path.exists() True boto3_package_path.is_dir() False boto3_package_path.is_file() True
Opening a "file" (s3 key):
.. code:: python
botocore_index_path = S3Path('/pypi-proxy/botocore/index.html') with botocore_index_path.open() as f: print(f.read()) """
Or Simply reading:
.. code:: python
botocore_index_path = S3Path('/pypi-proxy/botocore/index.html') botocore_index_path.read_text() """
s3path supports versioned objects for S3 buckets that have versioning enabled. VersionedS3Path is a subclass of S3Path that supports all of its features. The main difference is an additional required version_id keyword parameter in each of its constructor methods.
.. code:: python
from s3path import VersionedS3Path bucket, key, version_id = 'my-bucket', 'my-key', 'my-version-id' VersionedS3Path(f'/{bucket}/{key}', version_id=version_id) VersionedS3Path('/my-bucket/my-key', version_id='my-version-id') VersionedS3Path.from_uri(f's3://{bucket}/{key}', version_id=version_id) VersionedS3Path('/my-bucket/my-key', version_id='my-version-id') VersionedS3Path.from_bucket_key(bucket=bucket, key=key, version_id=version_id) VersionedS3Path('/my-bucket/my-key', version_id='my-version-id')
