Share data between IPython Notebooks

Question

If I have several IPython notebooks running on the same server. Is there any way to share data between them? For example, importing a variable from another notebook? Thanks!

Answer 1

This works for me :

The %store command lets you pass variables between two different notebooks.

data = 'this is the string I want to pass to different notebook' %store data

Now, in a new notebook… %store -r data print(data) this is the string I want to pass to different notebook

I've successfully tested with sklearn dataset :

from sklearn import datasets  dataset = datasets.load_iris()  %store dataset 

in notebook to read data :

%store -r dataset

Answer 2

Notebooks in Jupyter Lab can share the same kernel. In your notebook you can choose the kernel of another notebook and variables from the other notebook will be available in both notebooks.

1. Click on the button that describes your current kernel.
2. Choose the kernel of the other notebook, whose variables you want to access.
