Given that eglot has been part of the core emacs, I believe this is a long lasting wish for a lot of emacsers that has finally been fulfilled. (a stand alone DAP implementation that does not rely on LSP-mode)

    How would you attach a DAP python debugger to a running instance of (i)Python? Is there some import debugpy; debugpy.start() command or similar?

      I believe this is out of the scope of the DAP protocol, I believe even VSCode cannot do it based on my understanding.

      If you want to debug a running session, just use ipdb or pdb.

      There is

      In python:

      import debugpy
debugpy.listen(5678) # debugpy will open 5678

      Then add the following configuration to dape

      (add-to-list 'dape-configs
`(debugpy-attach
  modes ()
  host "localhost"
  port ,(lambda () (read-number "Port: "))
  :type "debugpy"
  :request "attach"))

      Supposedly there is a way to attach by pid with python3 -m debugpy --listen localhost:5678 --pid 12345, but that failed, both on osx and linux.
