Jupyter notebook is convenient for interactive coding, but sometimes I just need to view the code quickly in the terminal. I used to use nbconvert which is OK. Sometimes, it’s a little bit slow.

Now I use jupytext which feels faster in the terminal. Most of time, I don’t need the python file.

So I ask ChatGPT to write a bash function to view the jupyter notebook in the terminal without saving the intermediate python script. Below is the function. I added it into the .bashrc.

To use, jpyview your_notebook.ipynb.

# Function to convert a Jupyter Notebook to a Python script and open it in Vim
# with Python syntax highlighting
jpyview() {
    if [ "$#" -ne 1 ]; then
            echo "Usage: jpyview <notebook.ipynb>"
                return 1
                fi

                jupytext --to py "$1" -o - | vim -c "set filetype=python" -
            }
