If your course involves grading Jupyter Notebooks, all you need to do in codePost is include the .ipynb files in the codePost submissions. 

codePost will automatically render the Jupyter Notebook cells and output. From there, you write inline-feedback in the familiar format. 

To see it in action, checkout the video below.

Please note that the current Code Demo does not support Jupyter Notebook rendering. Please signup at https://codepost.io/signup to work with rendered file formats.
