Python package name normalization
CodeArtifact normalizes package names before storing them, which means the package names in CodeArtifact may be different than the name provided when the package was published.
For Python packages, when performing normalization the package name is lowercased and all instances of the characters
., -, and _ are
replaced with a single - character. So the package names pigeon_cli and
pigeon.cli are normalized and stored as pigeon-cli.
The non-normalized name can be used by pip and twine but the normalized name must be used in CodeArtifact CLI or API
requests (such as list-package-versions) and in ARNs. For more information about Python package name normalization, see
PEP 503
