import a function from another .ipynb file

Question

I defined a hello world function in a file called 'functions.ipynb'. Now, I would like to import functions in another file by using "import functions". I am sure that they are in the same folder. However, it still shows that "ImportError: No module named functions". By the way, I am using jupyter notebook. Thanks a lot!

Answer 1

You'll want to use the ipynb package/module importer. You'll need to install it: pip install ipynb.

Create a Notebook named 'MyFunctions'. Add a simple function to it.

def factorial(n):
if n == 0:
    return 1
else:
    return n * factorial(n-1)

Then, create a second Ipython Notebook and import this function with:

from ipynb.fs.full.MyFunctions import factorial

Then you can use it as if it was in the same Ipython Notebook:

testing = factorial(5)

See the documentation for more details.
