Debugging with Emacs 24 and IPython Breakpoints

I have now switched from Pjarcham to Emacs. Just wanted to use Emacs. Debugging with pdb is currently the main hurdle. I'm really scared of importing pdb; pdb.set_trace (). Last time I tried this debugging way using SublimeText and ended up with a lot of pdb.set_trace () in the code. Now when I move to Emacs I am looking for something.

• Best practics
• Is there any way in Emacs I can open some buffer just for debugging and not save it. Instead, I am modifying another copy that I will keep.
• Is there a way to debug any unsaved buffer in Emacs.

Kinldy will give me thanks. Noaman Faisal
