cloudpathlib.AzureBlobPath

Bases: CloudPath

Class for representing and operating on Azure Blob Storage URIs, in the style of the Python standard library's pathlib module. Instances represent a path in Blob Storage 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 AzureBlobClient class handles authentication with Azure. If a client instance is not explicitly specified on AzureBlobPath instantiation, a default client is used. See AzureBlobClient's documentation for more details.
