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 the byte compiled file is still present you may be able to reconstruct it, see here: https://stackoverflow.com/q/56817475/3279716 – Alex Oct 15 '21 at 21:47
  • Unfortunately this post did not help. I am still able to create new objects. So, notebook still knows what was happening in that class. Therefore, I believe there should be a way to get the source code of this class from jupyter notebook... but how... – Fatih Beyhan Oct 15 '21 at 22:24
  • You should look for a folder called `__pycache__` in there you might have a `parser.pyc`. You may be able to use a [python decompiler](https://stackoverflow.com/questions/5287253/is-it-possible-to-decompile-a-compiled-pyc-file-into-a-py-file) – Alex Oct 15 '21 at 22:33

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.
