I've created multiple python modules as .py files in a Python IDE called Pyzo in the following path:
'C:\Users\Michael\Anaconda3\Lib\site-packages' which I can then import like regular Python packages such as pandas and numpy into my Jupyter notebook or into Pyzo.
I'm a bit lost as to how to create a module in Jupyter notebook, containing a class with say a simple function, which I can then save and import into a new Jupyter notebook file.
The examples in this link below I found extremely vague and overly complicated. Any simpler examples would help, thanks!
http://nbviewer.jupyter.org/github/ipython/ipython/blob/master/examples/IPython%20Kernel/Importing%20Notebooks.ipynb
%run ./module_code.ipynb
keep this in import section- replace module_code with your file name and then you can access functions inside that file from the new notebook.
Suppose you want to import the contents of A.ipynb into B.ipynb.
Installation
pip install import-ipynb
How to use
Place both ipynb files in the same directory. Then, in the B.ipynb:
import import_ipynb
import A
Congratulations! You can now run any functions defined in A.ipynb from B.ipynb!
The easiest way to import user created modules on JupyterLab is to Export Notebook as an executable script from File menu as in screenshot. This will download .py file to your pc or mac. Just drag that downloaded file to your jupyterlab to import.
download notebook as .py file
Now you can import and use that module in other notebooks.

In jupyter notebook server, importing numpy or pandas is okay.

However, by using python3 or python in commandline, I am not able to import anything because of a package named SystemRandom. pic2
Can anyone give me some suggestions?
Much Appreciated!
You have a file random.py on your Users folder ("/Users/chenyao/random.py") this file is interfering with the numpy import. You have two options:
rename the file
change directory
It tries to import SystemRandom from /Users/chenyao/random.py. Remove or rename that file and it should work.
I am trying to load an excel file online.
This this my path directory.
C:\Users\Don.A.Charles\Downloads\Practice\sorted_data.xlsx
However, I am trying to load the file through Jupyter Notebook Online with no success
https://jupyter.org/try-jupyter/lab/
Can anyone suggest anything to amend the code to allow the program to load the data?
This is the code below
import pandas as pd
import numpy as np
from sklearn import preprocessing
import matplotlib.pyplot as plt
df=pd.read_excel(r"C:\Users\Don.A.Charles\Downloads\Practice\sorted_data.xlsx")
I am receiving the error
FileNotFoundError: [Errno 44] No such file or directory: 'C:\Users\Don.A.Charles\Downloads\Practice\sorted_data.xlsx'
You can not access local files from an online server like that.
You will need to upload the file to some storage that is accessible in https://jupyter.org/ or some external place (Google Drive/Drop box etc.) from where you can load it through http.
Sadly do not have enough experience with jupyter.org it self to know are they supporting file upload.
It might be a little daunting, but you'll have more flexibility if you run Jupyter locally, on your own machine.
The easiest way to do this is probably to install Anaconda. Then open an Anaconda prompt from the Start menu. Use the cd command to change directories to your project directory (e.g. a python_projects folder in your home directory, call it what you like). Then type jupyter notebook and now you're running locally. Then you can load the file with the command you were using before.
I am using jupyter notebook. I have 3 jupyter source files written in python in a folder in the same directory: parser, preprocess, and temp. I am trying to import parser and import preprocess in the temp file so that I can use the methods written in those files.
Example: there is method named extract in parser file. I want to use that from temp file. How can I do that?
The easiest way is to change the files you need to import as py files. As an example, parser.ipynb can be converted to a python file parser.py, and you can import it from another notebook file. If you want to use a function named extract() from parser.py, just import
from parser import extract
You can use pip for installing packages. Open command propmpt (cmd) and type this below command
pip install preprocess
You can run pip install preprocess from the terminal (or CMD, if you are using Windows). Alternatively, you can run ! pip install preprocess from Jupyter Notebook itself, which will do the same thing. You may need the second one if you are working on Google Colab.
I am trying to bring in a .py file that I have created and hosted in my Jupyter environment to a notebook. I have tried the following method, but it gives me an error.
import sys
sys.path.insert(0, '/path/to/file.py')
import file.py
I have several functions saved in this file that I want to be able to call, but when I run the above I get an error that the file.py was not able to be loaded in. Is there a special way within notebooks to load in created .py files?
I have a fully functioning jupyter notebook (.ipynb) file that can find and import both pandas and numpy. I also have that same exact code saved as a .py file in the same exact folder.
When I try to run the .py file with VSCode or Python Shell, I get an error message saying that numpy and pandas can't be found and aren't on path.
Not sure how the .ipynb file right next to it can find these modules but the .py file can't.
Any help would be much appreciated. (The .ipynb file runs through anaconda)
Since you are hosting jupyter notebook from conda it can easily use the same environment and able to find the pandas and numpy. Try import the same py file in jupyter notebook you will be able to execute the code. You need to specify python path to environment variables which is pointing towards the one which jupyter is pointing.
