Python package name normalization - CodeArtifact

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 in the Python documentation.
