are you executing after you have explicitly highlighted the code you are sending or just shift+entering on the line without any highlights?

[tttienthinh]

Hi Anthony, Thank you for your answer. I have tried both highlighting the code and just being on the line. Both ends up with a missing character.

@tttienthinh Are you using powershell, cmd, or any other terminal shell?

[tttienthinh]

I am using the PowerShell Terminal of VS Code I guess. This is what I get when I Shift+Enter for the first time :

PS C:\Users\...> & "C:/Program Files/Python312/python.exe"
Python 3.12.2 (tags/v3.12.2:6abddd9, Feb  6 2024, 21:26:36) [MSC v.1937 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

I feel like this might be related to: #24422 (comment) looking at the KeyboardInterrupt that is mentioned here.
Can you go to the referenced link and follow the steps to disable terminal shell integration and see if that helps?

Let me know how this goes, thanks!
