What are tmux and screen?

tmux: Terminal Multiplexer. It lets you create multiple virtual terminals within a single physical terminal window.
screen: Similar in concept to tmux, another popular option.
Benefits

Persistent Sessions: Even if you disconnect from your SSH session, sessions within tmux or screen persist. Your Python script will keep running.
Multiple Windows: You can split your terminal window into panes and switch between them, running different processes in each.
Reattachment: Reattach to a previous tmux or screen session whenever you log back in, and you'll find everything right where you left it.
