The realgud package (available from MELPA) supports PDB (among a gazillion other debuggers), and has a host of neat features that Emac's PDB doesn't have.

The one I like best is the shortkeys mode. Once you start debugging a program, you can press n, s, c etc. right in the source window, instead of having to type these commands in the PDB buffer. It also supports Visual-Studio style keybindings with function keys (f10, f11, f5, etc).

After installing RealGUD, you need to run M-x load-feature realgud to load it, and you can start pdb with M-x realgud:pdb.
