S3Path is a pathlib extension with AWS S3 Service flavour.
S3Path provide a Python convenient File-System/Path like interface for AWS S3 Service using boto3 S3 resource as a driver.
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.
The following example assumes an s3 bucket setup as specified bellow:
$ aws s3 ls s3://pypi-proxy/

>>> from s3path import S3PathListing "subdirectories" - s3 keys can be split like file-system with a / in s3path we:
>>> 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:
>>> 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:
>>> 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:
>>> 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()
TrueOpening a "file" (s3 key):
>>> botocore_index_path = S3Path('/pypi-proxy/botocore/index.html')
>>> with botocore_index_path.open() as f:
>>> print(f.read())
