Using smart send with REPL leads to NameError for every line of code

[John-Polo]

Type: Bug

Behaviour

Expected behavior: Inside a Python file, at a line, for example:
import numpy as np
use smart send ('shift+enter') to run REPL and watch code results. Move to next line and do the same thing.

Actual behavior: Editing in a Python file (.py) and using Smart Send with the VS Code REPL, each line of code sends as "deprecated", which in turn returns a NameError in the REPL window.

This doesn't happen in interactive sessions in the Python terminal in Code.

Steps to reproduce:

1. Start Code with 'code .' from cmd prompt window where I've activated a conda environment.
2. In current .py file in editor, use 'shift+enter' to run line.
3. Python REPL window prints "deprecated" and reports a traceback with error:
   Traceback (most recent call last):
   File "c:\Users\japolo.vscode\extensions\ms-python.python-2025.6.1-win32-x64\python_files\python_server.py", line 133, in exec_user_input
   retval = callable_(user_input, user_globals)
   File "", line 1, in
   NameError: name 'deprecated' is not defined
