How do I change the working directory used by pdb/gud?

Question

When running M-x pdb from Emacs, the current directory seems to be set to that of the directory of the script you are running, so

pdb ~/path/to/project/__main__.py

Would set the working directory to ~/path/to/project/. However, what if I need the working directory to be a different directory - say, one directory back? Is there a way to set the directory that pdb/gud uses as the "working directory"? At the first pdb prompt I can change the directory with os.chdir(), which works, but I would like to not have to do this every time. Thank you!

Update:

I have found that one potential solution would be to set gud-chdir-before-run (mentioned by @Nsukami_ below) to nil and then change to the desired directory with (cd "/path/to/directory") before running pdb. I tried doing this with the gud-mode-hook but the directory is changed too late. I have also, tried to do this with by advising pdb and gud-mode-hook, but don't yet have the lisp skills for this apparently...Is there a good way to call cd before gud-mode-hook/ before the dubugger starts?

Answer 1

import os; os.chdir('/path/to/dir');

To get know current working directory:

import os; os.getcwd();
