There is no specific support in ParaView for that use case, I’m afraid.
Out of curiosity, could you provide some code that shows what you are trying to do?

you can put three backquotes before the first line of code and three others after the last line, so it will be formatted as code.
example:
```
# some code
import os
…
```
will print
```auto
# some code
import os
...
```

I found the solution. It was just a standard output (the print() function ) that was giving me a problem.
