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 th

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 my_functions.ipynb. 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.my_functions 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.

Answer 2

You can save functions.ipynb as functions.py and can import the file as 'import functions'. Now you can use any function defined in the functions file as 'functions.function_name' For eg, if add is a function, functions.add(5,3) after importing will work.
