You can create a custom command like this:

;; PDB command line
(defun user-python-debug-buffer ()
  "Run python debugger on current buffer."
  (interactive)
  (setq command (format "python -u -m pdb %s " (file-name-nondirectory buffer-file-name)))
  (let ((command-with-args (read-string "Debug command: " command nil nil nil)))
    (pdb command-with-args)))
