cloudpathlib.S3Path

Bases: CloudPath

Class for representing and operating on AWS S3 URIs, in the style of the Python standard library's pathlib module. Instances represent a path in S3 with filesystem path semantics, and convenient methods allow for basic operations like joining, reading, writing, iterating over contents, etc. This class almost entirely mimics the pathlib.Path interface, so most familiar properties and methods should be available and behave in the expected way.

The S3Client class handles authentication with AWS. If a client instance is not explicitly specified on S3Path instantiation, a default client is used. See S3Client's documentation for more details.
