Save analysis with python script in a .larix project file

[MarcoVando]

Is it possible to save the analysis one can make with python scripts in a single larix file?
I'm currently saving the normalized and averaged data in separated .dat files using the write_ascii method but I was wondering if there's a way to save everything in a single project file.

I know about the save_session() method but it wants a _larch parameter which I don't know how to handle using python code and not larch code.

The save_session() function only really makes sense with a Larch session -- it saves the data and functions within that session.

A Python program can do many more things but has no general mechanism for "saving the whole state of a program".

You might be able to stuff all the data you have into a Larch session and then save that. That sort of depends on the processing you are doing and what you want to save.

I see
Yeah I'm currently exporting the files as ASCII and then I deal with them using list, dict etc....
Sort of the same thing.
Thank you

@MarcoVando Well, a session file saves all the arrays and other data for all the Groups in a session. It also saves the analysis results and fit histories in a way that can be conveniently restored. So, depending on what you are doing, it can be noticeably different from saving selected arrays to ASCII data files.

To me this is related to #411

@maurov Yeah, I agree.

A Larix file does have the Larch commands (almost Python ;)) from the session that got saved. But if you save a session, then open that do some processing and then save a new session, the older history of commands is not preserved [like, what if you open multiple session files and do some work].

Anyway, the simplest case of "turn session into script" is doable... hoping to work on more Jupyter examples today and tomorrow!

As a follow-up for this, I have created #524.
