With Python, you can just open a shell and quickly try out some code in a so-called REPL console. Guess what, you can do the same with Ansible. Browse your inventory, and even remote file systems in an interactive shell with ansible-console.

Ansible
Do you use Ansible? Maybe even in a pipeline or across teams? Chances are high that you might want to track your changes and last runs in a nice overview with ARA. Let's check out the nifty tool and investigate how it can help you with keeping on top.
Podman
Podman is the daemonless, rootless drop-in replacement for Docker. Furthermore, you can manage containers on a remote machine without connecting to it first. With Podman's remote capabilities, this is just a matter of configuration files.
