python-debugpy

Remote Python debugging uses debugpy to attach a client to an active process, inspect its state, and execute commands from an IDE. You attach to the running application and wait for the client to establish the session.

Post-mortem debugging analyzes an application's state after a crash by invoking pdb at the point of failure. It isolates issues in long-running services by allowing interactive inspection of the error context.

Yes, local Python debugging supports inline breakpoint insertion combined with the pdb interactive REPL. Running your script with pdb allows automated breakpoint exploration to diagnose application behavior.

No, local Python debugging only requires an environment with pdb available. Installing debugpy is optional and strictly necessary for enabling remote debugging sessions to attach to running processes.

Debugging multi-process Python applications combines post-mortem analysis and remote attachment via debugpy. This approach isolates issues across long-running services by attaching a debugger to inspect each process state.

Use debugpy for remote debugging to inspect running processes from an IDE, whereas pdb facilitates local interactive REPL sessions. The choice depends on whether you are diagnosing locally or attaching to long-running services.
