Do not use assert in production Ansible python code. When running Python
with optimizations, Python will remove assert statements, potentially
allowing for unexpected behavior throughout the Ansible code base.
Instead of using assert you should utilize simple if statements,
that result in raising an exception. There is a new exception called
AnsibleAssertionError that inherits from AnsibleError and
AssertionError. When possible, utilize a more specific exception
than AnsibleAssertionError.
Modules will not have access to AnsibleAssertionError and should instead
raise AssertionError, a more specific exception, or just use
module.fail_json at the failure point.
