python - Jupyter Notebook: Import .ipynb file and access it's method in other .ipynb file giving error

Question

I am fairly new to Jupyter Notebook. I have played around with it for a while. But this was my first time trying to import another notebook into my main class.

For reference, I am using Anaconda 4.3.1 and Python v2.7.

I am trying to replicate what I did in my python project to jupyter notebooks. It requires importing other .ipynb files (translated from the original .py files) into it to use relevant methods as desired.

For this, I followed the directions as given on Jupyter Nbviewer Steps Link which I found through my preliminary search on the following stack Question. It gave me some idea but didn't help me after one stage.

I will walk you through the steps I took and the sample program I tried.

1. Created a small .ipynb file abc.ipynb as follows

   def prt_n(str):
       print(str)
   if __name__ == '__main__':
       prt_n("in abc")
   

2. Created an .ipynb file to import Jupyter Notebook from the Jupyter link given above. Say, importer.ipynb.

3. Run importer.ipynb

4. import abc

5. str="Hello Me"

6. Test step abc.__name__ results in abc as output.

7. abc.prt_n(str) throws following error

*---------------------------------------------------------------------------

AttributeError                            Traceback (most recent call last)
<ipython-input-9-2fb88a43c9e5> in <module>()

----> 1 abc.prt_n(str) AttributeError: 'module' object has no attribute 'prt_n'*

I was hoping that the answer will be Hello Me.

Later, I want to actually create a myMain.ipynb file and in that I want to include 2-3 such notebooks and call their methods with required parameters.

One such example can be a file efg.ipynb as follows:

import abc a="Hello Notebook" abc.prt_n(a)

I also want to make sure if there is any other way to do this?

Note: I have already checked sys.executable and sys.path. Both have the same python path value.

Any sort of help is welcome!

Simple way to use ipynb files in jupyter note book are as follows:

1) Install import-ipynb

pip install import-ipynb

2) Import import_ipynb in jupyter notebook. Then import ipynb file as you import .py file

import import_ipynb
from test import print_name

print_name("your name")
