running this locally on your computer

• you should run this inside a virtualenv setup. A virtualenv is an isolated area to install 3rd party tools using what is in requirements.txt file. pip is the package manager to install 3rd party tools for python.
• Each operating system installation is a little different. See here for installing on each platform: mac/linux/windows
• once you have the python virtualenv activated we want to clone the repo:

mkdir ~/git/
cd ~/git/
git clone git@github.com:thesheff17/pythonexamples.git

• now create a virtualenv for this project. Always use a virtualenv env.

mkdir ~/.virtualenv
cd ~/.virtualenv
python3 -m venv pythonexamples
source pythonexamples/bin/activate

• now lets install the pip packages:

cd ~/git/pythonexamples
pip install -r requirements.txt

• you can always see what packages are installed with:

pip freeze

• now run the juypter notebook:

cd src
juypter notebook

• The juypter notebook should automatically launch your web browser and visit the correct url. if it doesn't copy paste the url from the terminal that starts with: http://127.0.0.1:8888/. If you get any errors make sure your virtualenv is activated and pip packages are correct. Below is an example of my output after starting juypter.

[I 06:32:16.576 NotebookApp] Serving notebooks from local directory: ~/git/pythonexamples/src
[I 06:32:16.576 NotebookApp] The Jupyter Notebook is running at:
[I 06:32:16.576 NotebookApp] http://localhost:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
[I 06:32:16.576 NotebookApp]  or http://127.0.0.1:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
[I 06:32:16.576 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 06:32:16.585 NotebookApp]

    To access the notebook, open this file in a browser:
        file:///~/Library/Jupyter/runtime/nbserver-43778-open.html
    Or copy and paste one of these URLs:
        http://localhost:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
     or http://127.0.0.1:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
