I'm using Jupyter Notebooks within Google CloudDatalab in Google Cloud Platform for my Python scripts. This creates .ipynb files.

I want to be able to create Modules and Packages using Jupyter Notebooks but it is not able to import the scripts.

For e.g.:

mymodule.ipynb has this:

def test_function():
    print("Hello World")

Then in myscript.ipynb when I try to import the above:

from mymodule import test_function

It throws an error :

*ImportErrorTraceback (most recent call last) in ()

----> 1 from mymodule import test_function ImportError: No module named mymodule*

How do I create Modules & Packages using Jupyter Notebooks?

Notebooks can't be used as modules. You need to create a python file (e.g. mymodule.py).

If you want you can do this from within a jupyter notebook:

with open('mymodule.py', 'w') as f:
    f.write('def test_function():')
    f.write('    print("Hello World")')

from mymodule import test_function
test_function()
# Hello World

You cannot import Jupyter Notebook in the same way as Python files (packages).

Check this link: https://jupyter-notebook.readthedocs.io/en/stable/examples/Notebook/Importing%20Notebooks.html

I've received a response on a different forum which answered my question. Here is the answer:

Put your module code into a .py file and make sure that's in the same directory as myscript.ipynb. To create the .py file from the code currently in a notebook, you can download it from within Jupyter as a .py file and tidy it up in your text editor of choice. Remember, the import statement is pure python syntax. It knows nothing about - and has no wish to know anything about - jupyter notebooks. It's looking for a .py file.

This has resolved the issue.

Thanks a lot.
