i am not a python devloper but i can fugre bits and peices out…
as a multi devloper im faced with code in all formats :: so i often forget a lot!! so i need help to be able to execute code on a jupiter notebool from a python app and return the value of the executed cell:
so i would like to be able to send a few cells as a lest then execute them interactivly ie : cell 1-5 then cell 8 … returning the results :
I understand that some how to go the Ipython route for this ? but cannot fiugure it out can yuou help ?

Obiously i know how to use jupiter notebook but i dont want to use it directly , but programatically :

I need to be able to run a cell from a python script on the ipython kernal and return the output from the function sent < hence the function would be sent as a string to the ipython(ikernal) or jupyter_client and return the value , pass/ fail / output … verbose on/off….

so to use the jupyter_client to even execute a script on the operating system using a magic command sending it to the jupyter client to return the result could be the output from an installation via pip or even a project directory listing….but also it can be a code output , hence also it could be a custom environmnet ( loaed in a virtual jupiter notebook, items imported , code executed , result returned) …in a clean environment (could be volitile and destructable hence not held or kepy , as well as could be a prewritten jupyter notebook file , or simply a python script?)..
today we recive a lot of mixed scripts containing markdown and code and often we do not have time to sift through documents or keep writing mad funcitons to extract specific code fragments from code .. but ipython can handle these mised code snipptes of markdown and pycode or other lisp/rust/r/ etc which can all be ru on a note book … hence from a python app r code can be executed in a cell and its output returned to the original python app !
hence the requirement for this funcitonality as it enables mulit code develoopment strategeies :

Today this is also used in fucntion calling for llm large lang models etc !

it will also open the understanding of how to be utilizing the ipython from a windows console app (.net) (VB.NET) – so i can use python in my prime programing languge VB.NET(utilizing python.net) …

Sorry for the long post but its important to fully outline my quesion :

im totally confused which item to be using …. Jupiter client ? pyNotebook, ikernal, ipython ?
the api information is confusions
