In what follows python is an alias for python3.6 or pypy3.6
or any later version (python3.7, pypy3.7 and so on).

TrueInstall bump2version.
Choose which version number category to bump following semver specification.
Test bumping version
bump2version --dry-run --verbose $CATEGORYwhere $CATEGORY is the target version number category name, possible
values are patch/minor/major.
Bump version
bump2version --verbose $CATEGORYThis will set version to major.minor.patch-alpha.
Test bumping version
bump2version --dry-run --verbose releaseBump version
bump2version --verbose releaseThis will set version to major.minor.patch.
