Error with multiple statements python chunks from file

[Atrebas]

The following code works when code2 contains a single statement.
It fails if it contains multiple statements, that otherwise are executed correctly if provided directly in the Rmd document.
Both cases work fine with R.

```{r}
library(knitr)

# works with a single statement
# cat("## @knitr  code2\nprint(1+1)", file = 'file.py', append = FALSE)

# fails with multiple statements
cat("## @knitr  code2\nprint(1+1)\nprint(1+1)", file = 'file.py', append = FALSE)

read_chunk('file.py')
```

```{python}
print(1+1)
print(1+1)
```


```{python}
<<code2>>
```

The error is:

Quitting from lines 25-26 (tmp.Rmd)

Thanks.

Fixed in knitr. You can install the development version via

remotes::install_github('yihui/knitr')

Thanks for the report!

Thanks for the quick fix! Sorry for the confusion with knitr.

Me again. FYI, there is an error when python chunks contain comments only.
