Jupytext Convertion Failed to Recognize Code Blocks

[HumphreyYang]

Hi @mmcky,

I found Jupytext failed to convert

```{code-cell} python3
...
```

to code blocks in .ipynb for the Markov chain lecture. Is it a bug, or is it meant to be like that by design?

hey @HumphreyYang. I wonder if it is because of the python3 rather than ipython?

[mmcky]

Thanks @HumphreyYang it was the headers in jupytext so I will close this now
