How to create an SHA-512 hashed password for shadow?

The previous SF questions I've seen have lead to answers that produce MD5 hashed password. Does anyone have a suggestion on to produce an SHA-512 hashed password? I'd prefer a one liner instead of a script but, if a script is the only solution, that's fine as well. Update Replacing previous py2 versions with this one: python3 -c "import crypt;print(crypt.crypt(input('clear-text pw: '), crypt.mksal

“python -c 'import crypt; print crypt.crypt("test", "$6$random_salt")'”
