Python matplotlib interactive mode on by default
reddit / emacs

Hi everyone,

currently, I run `plt.ion()` (with plt as `import matplotlib.pyplot as
plt`) anytime I want an interactive `matplotlib` plot. Which is quite
inefficient.

I would therefore like to set the `matplotlib` interactive mode on by
default for any python code I run, without having to specify it... But
couldn't find the solution so far...!

I set my ipython in emacs with:

`;; (setq python-shell-interpreter "ipython3" python-shell-
interpreter-args "-i --simple-prompt")`

Thank you a lot in advance for your help!

This can be done by just configuring a startup script on ipython.

Thank you. I thought this could also be done in my emacs config but at
the end I indeed went for a `plt.ion()` that I added in my
`~/.ipython/profile_default/startup.py` Thanks!

Glad I could help. There might be a way to do it from emacs (as emacs
is almighty!) but I wouldn't know that, as I'm kind of a noob myself.

You can also use `inferior-python-mode-hook`.
