Command-Line Interface¶

The dataexcept package bundles a small CLI that lets you inspect the exported exception classes and verify which version of the library is installed.

Quickstart¶

You can invoke the CLI either through the dataexcept entry point or directly via python -m:

$ python -m dataexcept list
JobError
ValidationError
...

This is helpful when running inside virtual environments where the console script might not be on PATH.

Listing Exceptions¶

Packages often add new exception groups over time. Rather than maintaining a hard-coded list, the CLI dynamically walks the dataexcept package and prints every class that ends with Error:

$ dataexcept list
JobError
DataScienceError
PipelineError
...

Because the discovery step looks for any submodule that exposes __all__, new exception modules automatically appear in the output as soon as they are released.

Version Information¶

Use the --version flag to check which build you have installed:

$ dataexcept --version
dataexcept 1.0.0

This is useful inside CI pipelines where you want to confirm that the workflow has downloaded the expected artifacts.
