Use of """ in docstrings does not work in org src block

[fraricci]

I wanted to share this issue I recently found. Not sure this has been discussed already.

Here a simple example of code that generate an error:

#+begin_src jupyter-python
class Example():
    """docstring"""

#+end_src

#+RESULTS:
:RESULTS:
# [goto error]
:   Cell In[155], line 5
:     get_ipython().run_cell(r"""class Example():
:                            ^
: SyntaxError: invalid syntax. Perhaps you forgot a comma?
:END:

The way I found to avoid this is to replace """ with '''.
I believe the use of """ is recommended or at least very common.
Is there a way to fix this? Or there's something broken in my org config.

Thanks!

testing a little more I found that a possible cause of this is setting the option :dir (which I had set in the #+PROPERTY: in the example above).

#+begin_src jupyter-python :dir ./ 
class example():
    """docstring"""

print("test")
#+end_src

#+RESULTS:
:RESULTS:
# [goto error]
:   Cell In[22], line 5
:     get_ipython().run_cell(r"""class example():
:                            ^
: SyntaxError: invalid syntax. Perhaps you forgot a comma?
:END:

without :dir, it works fine

#+begin_src jupyter-python
class example():
    """docstring"""

print("ciao")
#+end_src

#+RESULTS:
: ciao

Also, this happens in similar way:

#+begin_src jupyter-python :dir ./
var = "test"
#+end_src

#+RESULTS:
:RESULTS:
# [goto error]
:   Cell In[32], line 5
:     get_ipython().run_cell(r"""var = "test"""")
:                                              ^
: SyntaxError: unterminated string literal (detected at line 5)
:END:

here, removing the :dir flag works, but also adding a newline or a space after the var = "test" fixes the issue even keeping the :dir flag

#+begin_src jupyter-python :dir ./
var = "test"

#+end_src

#+RESULTS:
