I am experiencing unexpected behavior when running cells in Jupyter Notebook within VS Code. The output of a cell seems to persist across multiple executions, and certain expressions do not produce the expected visible output.

Issue 1: Outputs Persisting Across Runs

When I run a cell multiple times, its previous outputs remain visible instead of being replaced by the latest result. For example:

hello = "hello"
hello

I expect to see only "hello" when I run the cell. However, each execution appends to the output history instead of clearing the previous results.

Issue 2: Lists Not Displaying Without print()

Normally, in Jupyter Notebook, calling a variable should display its value in the output without requiring print(). However, when I execute:

b = [5, 10, 15, 20, 25]
b

I get an empty output instead of seeing the list [5, 10, 15, 20, 25]. Using print(b) does work, but I expect b alone to display the list as it does in a typical Jupyter Notebook environment.

What I Have Tried

• Restarting the kernel

• Running the notebook in a different environment

• Looking for relevant settings in VS Code (I couldn’t find any that change this behavior)

Is this a known issue with Jupyter in VS Code? Are there any configurations or fixes that would restore normal Jupyter output behavior?

Environment Details:

• Editor: VS Code

• Jupyter Extension: Installed and up to date

• Python Version: 3.12.7 (using Anaconda base environment, but this persisted also without Anaconda)

• Jupyter Notebook Version: 2024.11.0

Any insights or solutions would be greatly appreciated!
