Thing is, I like my zsh. Sometimes I use Nu shell as well, which does structured data better. Serialization I think needs to happen anyway to get data into IPython from outside. I have tried Xonsh once or twice, but it was too large change. Unix shell does some things very well, Python I like to use for other things. It is the crossover I’d like to smooth out.

I am confused on what having a persistent Python process means in this context. Isn’t IPython already that? Jupyter console states it’s a single process IPython terminal. That does leave me wondering what is different when I start IPython vs Jupyter console. I might have assumed years ago that they are mutually exclusive…
