Using Jupyer notebook as python application

Not too long ago i accidently discovered that Jupyer is just a python package that you can download and use.
Having good environment for interanctive programming in few commands on almost any device with python installed is really handy
It is simple to set up if you work in python on daily basis or used terminal a bit.

Prerequisite

• python3
• pip3

How to create virtual python environment

Installing packages randomly on system is kinda dumb idea.
Let’s create python venv (virtual environment)

python -m venv my_venv
# you can change name to something else

How to activate venv

After python create venv you can activate it in current shell

# on linux
source my_venv/bin/activate
# or 
. my_venv/bin/activate

shell prompt should change
in my case:

# before:
talandar@gentoo ~ $
# after:
(my_venv) talandar@gentoo ~ $

Installing jupyter

we can now use python package manager called pip to install jupyter

pip install jupyter

Running jupyter notebook

to run jupyer notebook just type this:

jupyter notebook 

observe log for link to website
it will look like this:

Or copy and paste one of these URLs:
    http://localhost:8888/tree?token=sometoken....
    http://127.0.0.1:8888/tree?token=sometoken....

paste in your browser and you are ready to go

TLDR

# create and activate venv
python -m venv my_venv
. my_venv/bin/activate
# install jupyter
pip install jupyter
# run jupyter notebook
jupyter notebook 
# observe logs for link to page
Or copy and paste one of these URLs:
    http://localhost:8888/tree?token=sometoken....
