Jupyter Inheritance

Inherit Jupyter Kernels

You have a notebook base.ipynb with a cell

import os
from datetime import datetime

class Test:
    msg = "Hey!"

def add(x, y):
    return x + y
    
test = Test()
now = datetime.now()

that has been executed. You can create a new notebook and run the following code:

from jupyter_inheritance import inherit_from
inherit_from("base.ipynb")

assert add(1, 4) == 5
assert isinstance(test, Test)

print(test.msg)
print(now)  # same value as `now` in `base.ipynb`!
print(os.listdir("."))

The base.ipynb content is not executed from scratch in the new notebook, all the existing objects are copied directly from base.ipynb kernel. This ensures that everything stays exactly the same (e.g. timestamps, random numbers, responses from externals APIs).

You can even do mixins!

from jupyter_inheritance import inherit_from
for notebook in ("base_1.ipynb", "base_2.ipynb"):
    inherit_from(notebook)

Installation

Just the usual

pip install jupyter-inheritance
