when I press SHIFT + ENTER, or right click selection -> Run Python -> run selection/line in the python terminal it opens 2 terminals

[pkoprov]

Type: Bug

when I press SHIFT + ENTER, or right click selection -> Run Python -> run selection/line in the python terminal it opens 2 terminals named Python, where the first one opens the python terminal (PID 29056) but the second (PID 434444) does not. After that, it tries to execute the highlighted code in the second terminal which obviously is yielding an error.
If I kill the second Python terminal (PID 434444) and try to run a line of Python again, it opens a new terminal with a new PID and no Python console and behaves exactly like the second one.
If I kill the first terminal and then run the line it does not create another console, but still not running the code.
Finally, if I type python in the second console it opens the python terminal, and if I start running line-by-line execution it works.

I have got the same issue after I upgraded to v2023.10.0.
When trying to run the selected codes by pressing Shift + Enter -> end up with two terminal windows open:

1. The first terminal window just activates Python and no follow-up executing the selected codes.
2. The second terminal is just the default terminal with those Python codes with no python environment.

As someone tipped you there, try rolling back to v2023.8.0 of the vscode-python extension.

Some bug appeared in the latest version, it seems.

[dirk2011]

Related on Stack Overflow:

• When I 'Run Selected' in Python on Visual Studio Code, it is suddenly opening up two Python terminals, one of which does not run my Python code I've written an answer post here with the current workaround of rolling back. Once the cause is known and the fix is made, I'll update this post.
• VS Code run selection in terminal creating multiple shells Once allowed by the Stack Overflow system, I'll vote to close this one as a duplicate of the above.
• Why opens Visual Studio Code a second Python terminal and breaks the first? another one.
• Problem: Visual Studio Code has 2 Terminals and is defaulting to one of them which is not desired and another one.
• shift+enter shortcut not working for vscode and another another one.

If you have the privilege level to do so, help with closing duplicates would be appreciated, so the answers can be put in one place instead of scattered about.

Was also facing this issue. Rolling back to v2023.8.0 seemed to help.

same issue for me, thank you @starball5, rolling back really helps

I just wanted to quickly apologize for the breakage! #21418 has been opened to revert this new terminal feature to fix this breakage. Unfortunately none of our pre-release users ran across this (been in main since May 10, so available in pre-release since May 11; obviously if anyone here is interested in using pre-release versions, more help is always appreciated 😁), and we seem to have a gap in our tests around this flow (which I have opened #21420 to fill that gap).

Our hope is to have a bugfix release out today or tomorrow depending on how the revert PR goes.

@brettcannon I tried a prerelease version after 10 release, and it had the same problem, so I had to rollback to version 8.

I just wanted to say I accept your apology, 😉. I'm thankful to the open source community that builds software that all of the rest of us lurkers use daily without a second thought and we only come out of the woodwork to complain when something goes wrong. You developers are heros, even if you occasionally introduce bugs, 😝.

So really, I accept your apology, and rather I thank you for your efforts to maintain these amazing free resources for us all!

I'm looking forward to the fix, 😊.
