Execute code in Quarto Document

[Nicky-Jin]

Type: Bug

I have both code cells of Python and R. However, when I click the "Run Cell" above the code cell, it is always excuted in R, even if it is a Python cell. For example, my code cell like:

import numpy as np
import pandas as pd
import scanpy as sc
import os
os.getcwd()

I have specified the code type with ```{python}

If I click "Run Cell", it will run in R console and report error.

Thanks for reporting @Nicky-Jin !
I believe this is related to: #3865

What's happening is that the Quarto extension is sending the python code to the R console using:

reticulate::repl_python(input="<chunk code> ")

And positron renders it in the R console. With #6529 the code will be sent to the Reticulate Python console.
