Doom-emacs: +python/open-ipython-repl buffer does not support multiline scripts

[0liu]

What did you expect to happen?
When starting an inferior iPython process buffer by +python/open-ipython-repl, it should behave the same as in IPython in a regular terminal emulator, i.e., one can code scripts or define a function in multi-line form, such as:

In [7]: for i in range(5): 
   ...:     print(i) 
   ...:

or

In [8]: def print_i(n=5): 
   ...:     for i in range(n): 
   ...:         print(i) 
   ...:                                                                                                                                        

What actually happened?
NameError was raised:

In [2]: for i in range(10):
   ...:     print(i)

According to this Reddit thread, setting the variable (setq python-shell-prompt-block-regexp "\\.\\.\\.:? ") in ~/.doom.d/config.el fixed it. Should this setting be added to Doom Emacs by default?

I have tried this solution with the normal python repl (default), jupyter and ipython repl as such:
(set-repl-handler! 'python-mode #'+python/open-jupyter-repl)
(set-repl-handler! 'python-mode #'+python/open-ipython-repl)

I still get weird indenting errors when executing a whole script with gr.

The only repl that seem to work for python in doom emacs with a send-region-to-repl functionality is using the emacs-jupyter package. But that package this not seem to be very well integrated with doom. Or at least, i haven-t figured out how...
