The return type is typed as :class:`NormalizedLicenseExpression`. This allows type checkers to help require that a string has passed through this function before use. :param str raw_license_expression: The License-Expression to canonicalize. :raises InvalidLicenseExpression: If the License-Expression is invalid due to an invalid/unknown license identifier or invalid syntax. .. doctest:: >>> from packaging.licenses import canonicalize_license_expression >>> canonicalize_license_expression("mit") 'MIT' >>> canonicalize_license_expression("mit and (apache-2.0 or bsd-2-clause)") 'MIT AND (Apache-2.0 OR BSD-2-Clause)' >>> canonicalize_license_expression("(mit") Traceback (most recent call last): ...
