I'm not python expert, but the code block should be run in your current
directory, e.g., the following outputs the current working path expected
for me.
#+begin_src sh
pwd
#+end_src
If you want to explicitly pass the current directory to your code block
as an argument, you could try something like the following
#+begin_src python :var mydir=(file-name-directory (buffer-file-name))
return mydir
#+end_src
Hope this helps,
