python-debugpy

Remote Python debugging allows you to attach to an existing process without restarting it. You use debugpy.listen to open a port on the running process and connect a client to inspect the state and investigate failures.

Combining pdb with remote debugging in Python involves using debugpy to listen for a client connection while inserting pdb breakpoints to interactively inspect the running code during your session.

Post-mortem debugging in Python lets you inspect state after a failure. By attaching debugpy to the process or launching with --listen, you can investigate the context of the crash without needing a restart.

Yes, remote Python debugging with this approach requires installing the debugpy package. You use its listen and wait-for-client functions to establish the connection before interacting with pdb breakpoints.

Debugging a headless or long-running Python service uses remote debugging via debugpy. You attach a debugger to the running process by listening on a port, enabling state inspection without interrupting the service lifecycle.
