IPython magic commands need to be runnable from comments so other tools can work with them.

Including magic commands in an interactive python file breaks automatic code formatting. For instance, this

#%%
%load_ext autoreload
%autoreload 2

#%%
a,b,c = [1 , 2 , 3]

will only be formatted to

#%%
# %load_ext autoreload
# %autoreload 2

#%%
a, b, c = [1, 2, 3]

if the magic commands are commented out. It would be nice if magic commands didn’t throw off the formatter, at least if the file contains #%% cell delimiters.

Are you suggesting this? #! - shell assignment #!% - line magic #!%% - cell magic

I think that would work. At least I can’t think of a better idea.

So are you asking for a new feature - run magics in comments?
