I am trying for a long time a way to run pdb from emacs and have the 
code synchronized.

I searched google for emacs+python+debug or emacs+pdb but the 
instructions would say: "M-x pdb" but then emacs asked the command line 
to run the debug and I tried "pdb" "pydb" "pydb filename" but nothing 
worked.

When I tryed "M-x pdb" then "pydb" I need to use "file <filename>" (and 
the completion doesn't work here for the filename), then the debugger 
worked, but no sync with the source code :-(

 From the help of GUD, I tried "M-x pdb <RET> FILE <RET>" also without 
success.

Anyone can help me with this? I really don't know how to make it work. I 
have seen in the python-emacs-mode that there are some code to 
synchronize the code, but I could not make it work in this way (I don't 
know enough elisp) :-(

But anyway, thanks Chris for the tip. This one worked for me :-) It is 
possible to set breakpoints using the source buffer instead of using the 
line number?
