Function Documentation

_version_join()

str packaging.specifiers._version_join ( list[str]  components )

protected

Join split version components into a version string.

This function assumes the input came from :func:`_version_split`, where the
first component must be the epoch (either empty or numeric), and all other
components numeric.

_version_split()

list[str] packaging.specifiers._version_split ( str  version )

protected

Split version into components.

The split components are intended for version comparison. The logic does
not attempt to retain the original version string, so joining the
components back with :func:`_version_join` may not produce the original
version string.
