With LSP, how to get an "input()" in python that works when entering data using the keyboard

Question

Here is a minimal example:

I created and activate a virtual environment:

~/BacSable/bac2 $ mkvirtualenv minimal_env



created virtual environment CPython3.10.5.final.0-64 in 651ms
  creator CPython3Posix(dest=/Users/raoul/.virtualenvs/minimal_env, clear=False, no_vcs_ignore=False, global=False)
  seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/Users/raoul/Library/Application Support/virtualenv)
    added seed packages: pip==22.1.2, setuptools==62.6.0, wheel==0.37.1
  activators BashActivator,CShellActivator,FishActivator,NushellActivator,PowerShellActivator,PythonActivator

My script minimal.py contains:

print("yes I can print")
my_input = input("Do you have a problem? (copy paste your answer)")
print(my_input)
my_input = input("Do you have a problem? (type your answer)")
print(my_input)

Completion works well with LSP in the script buffer. With C-c C-z I can switch from script to console and vice-versa.

With C-c C-c I run the script and I encounter this problem:

The input works if I copy-paste to enter an answer. However, if I type it, I get an error:

yes I can print
Do you have a problem? (copy paste your answer)yes
yes

The interpreter behaves as if I typed >>>yes directly (instead of just passing it to input() ):

>>> yes
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'yes' is not defined
>>> 

Of course I can execute the script from eshell:

Welcome to the Emacs shell

~/BacSable/bac2 $ python minimal.py 
yes I can print
Do you have a problem? (copy paste your answer)yes
yes
Do you have a problem? (type your answer)yes
yes
~/BacSable/bac2 $ 

Or

~/BacSable/bac2 $ python -i minimal.py 
yes I can print
Do you have a problem? (copy paste your answer)yes
yes
yes
Do you have a problem? (type your answer)yes
yes
yes
>>> my_input
my_input
'yes'
>>> 

But is there a way to make reading input work by running the script with C-c C-c?

Answer 1

The problem came from

(add-hook 'after-init-hook 'global-company-mode)

To solve the problem, I modified the activation of company in order to deactivate the mode when we are in the python console launched by C-c C-c :

(use-package company
  :ensure t
  :config
  (add-hook 'after-init-hook 'global-company-mode)
  (add-hook 'inferior-python-mode-hook (lambda () (company-mode -1)) 'append)
  ;; The append argument ensures that it's added to the hook after other functions
  )
