Adding more details. BTW, no issues at all (none of the two, as it looks like there may be two different issues) if I just do:
(advice-add 'python-shell-send-string :override #'python-shell-send-string27)
where 'python-shell-send-string27 is the python-shell-send-string function from emacs 27.2.
(regarding the backtrace, I realize it's hard to read - is there a better way to send it formatted in this thread?)
Hi!
Thanks for the response!
I'll fill in the details shortly. I wanted to add to the bug, that the functions being called repeatedly were `python-shell-send-string` and `python-shell-send-file`.
They call one another and create more and more temporary files before I get the recursion error.
As a side note, python.el really rocks. Thanks so much for the amazing work.

Hi,
Can you try 'M-x toggle-debug-on-error', or maybe tracing some
functions, to discover what is being called repeatedly?
Also, what happens if you (setq python-eldoc-get-doc nil) in the .py
file's buffer?
I'll try this asap. I thought it was eldoc, but then tried turning off 'eldoc-mode' off and I still had the same problem with the infinite recursion (and I think I still saw the weird PYDOC strings, but not sure).
But I will try this today.
This did not change anything to the nested lisp error, but does remove the prints of "def __PYDOC_get_help(obj)". So it looks like there may have been two different issues here.
Some more macos-related things that would be helpful to know:
* On a freshly started python-shell, is are the functions
__PYTHON_EL_eval and __PYTHON_EL_eval_file defined?
I just checked, and they both are.
<function __main__.__PYTHON_EL_eval(source, filename)>
<function __main__.__PYTHON_EL_eval_file(filename, tempname, delete)>
* If you do M-x python-shell-send-string RET x="aaa...aaa" or something
like that, can you evaluate Python statements that are, say, 900 and
1100 characters long?
Will try this immediately
So, interesting, if I write
x = "aaa....a" in my py file (calling python-shell-send-string interactively doesn't work like that, shoud it?), it works for len(x) = 422 and not for len(x)=423 (same error "nesting exceeds").
