Question

Is it possible to have jupyter nbconvert ... --to script ignore markdown cells rather than convert them to comments?

I'm asking because I want to use flake8 to check the Python code that's generated

You can do this directly with nbqa :

$ nbqa flake8 my_notebook.ipynb --extend-ignore=E203,E302,E305,E703
my_notebook.ipynb:cell_3:1:1: F401 'import pandas as pd' imported but unused

It also works as a pre-commit hook, see https://nbqa.readthedocs.io/en/latest/pre-commit.html
