importing functions from another jupyter notebook

Question

I am trying to import a function from another jupyter notebook

In n1.ipynb:

def test_func(x):   return x + 1 -> run this 

In n2.ipynb:

%%capture %%run n1.ipynb test_func(2) 

Error:

NameError Traceback (most recent call last)<ipython-input-2-4255cde9aae3> in <module>() ----> 1 test_func(1)  NameError: name 'test_func' is not defined 

Any easy ways to do this please?

Answer 1

The nbimporter module helps us here:

pip install nbimporter 

For example, with two notebooks in this directory structure:

/src/configuration_nb.ipynb

analysis.ipynb

/src/configuration_nb.ipynb:

class Configuration_nb():     def __init__(self):         print('hello from configuration notebook') 

analysis.ipynb:

import nbimporter from src import configuration_nb  new = configuration_nb.Configuration_nb() 

output:

Importing Jupyter notebook from ......\src\configuration_nb.ipynb hello from configuration notebook 

We can also import and use modules from python files.

/src/configuration.py

class Configuration():     def __init__(self):         print('hello from configuration.py') 

analysis.ipynb:

import nbimporter from src import configuration  new = configuration.Configuration() 

output:

hello from configuration.py
