Run from and save to .py file from Jupyter Notebook
A text file can be loaded in a notebook cell with the magic command %load.
If you execute a cell containing:
%loadpy filename.py
The content of filename.py
will be loaded in the next cell. You can edit and execute it as usual.
To save the cell content back into a file add the cell-magic
%%writefile filename.py
at the beginning of the cell and run it.
To see the help for any magic command add a ?
: like %loadpy?
or %%writefile?
.
%COMMAND-NAME?
i.e. %run?
For list of available magic function use %lsmagic
.
Alternatively there is also another method magic function called %save-f
but I would not recommend that, it's an indirect way of saving files.

Hope this helps.
This is not the exact answer. At one point, I was able to open .py files using python notebook and work on it as if it were a notebook file.
However, I have been able to replicate this behavior using VScode.
https://code.visualstudio.com/docs/python/jupyter-support-py
Using VScode, you can export all your .ipynb files into .py files, then run code blocks. Code blocks are separated by # %%
.
I have not used it sufficiently long enough to decide if it is better than python notebook, but this seems to be the best solution so far. I previously tried using Atom/Hydrogen and did not enjoy the experience.
