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.

Install:

From PyPI:

.. code:: bash

$ pip install s3path

From Conda:

.. code:: bash

$ conda install -c conda-forge s3path

Basic use:

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()) """ <!DOCTYPE html>

Package Index botocore-1.4.93.tar.gz

"""

Or Simply reading:

.. code:: python

botocore_index_path = S3Path('/pypi-proxy/botocore/index.html') botocore_index_path.read_text() """ <!DOCTYPE html>

Package Index botocore-1.4.93.tar.gz

"""

Versioned S3 Objects:

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')

New in version 0.5.0
