Question might seem confusing but let me explain.

I was working on a jupyter notebook. I had some of my functions and classes in .py files that I was using with importing them in the notebook. I accidentally deleted (rm) these .py files. However, they are still imported in jupyter notebook. Can I restore the code that exists in these .py files from jupyter notebook.

Details with example:

I had parser.py file.

I imported the class that I was going to use

from parser import Parser

I can still user Parser class, however, parser.py is gone. Hence, whenever I will stop this notebook. I will lose Parser forever...

If you can continue to modify the notebook where you have parser imported, you can try:

import inspect
print(inspect.getsource(parser))

This should print the contents of the module that was loaded when you originally imported Parser from parser.py. If that doesn't work, try replacing parser with Parser.
