Remote debugging with debugpy allows you to attach to a running Python process without restarting it. This is ideal for long-running services or daemons where pausing execution helps diagnose issues in real-time.

Post-mortem debugging allows you to inspect local variables and the call stack at the exact moment a Python application crashes. Using pdb or debugpy, you can pause execution at the crash point to diagnose unhandled exceptions.

Yes, pdb provides a REPL for local Python script debugging, enabling you to insert breakpoints and step through code. It supports direct script execution for quick inspection and diagnosis.

Yes, remote debugging requires debugpy to be installed in your Python environment. You need it to attach a debugger to running processes, long-running services, or subprocesses for live diagnosis.

You can set breakpoints in Python subprocesses using debugpy for remote debugging attachment. This enables pausing execution and inspecting variables across processes to pinpoint issues in complex applications.

The best way to inspect locals at a crash point is post-mortem debugging using pdb. It drops you into an interactive REPL at the exact failure location, allowing immediate inspection of local variables and application state.
