Now:
$ python3

>>> import sys
>>> from launchpadlib.launchpad import Launchpad
>>> def no_credential():
... print("Can't proceed without Launchpad credential.")
... sys.exit()
...
>>> launchpad = Launchpad.login_with('Test', 'production', credential_save_failed=no_credential, version='devel')
>>> me = launchpad.me
>>> me.getPPAByName(name="openjdk")
