Safely close the notebook by clicking “File” –> “Close and Halt” before closing your browser.
Local Python installation#
Despite the many cloud-based Python Jupyter Notebook solutions, it is always good to have a local installation on your own computer. Point your web browswer here to install Python Anaconda distribution 3.9 (as of January 2022): https://www.anaconda.com/products/individual
Download the installation file for your operating system, open it, and follow the instructions to install.
Once installation completes, open the application named “Anaconda Navigator”. It looks like this:
Click the “Launch” button under either Jupyter Notebook or Jupyter Lab.
Open the
.ipynb
notebook you just downloaded from JupyterLab in your local installation and repeat the steps above.

Click the green “Code” button
Click “Download ZIP”
Extract this folder someplace familiar such as your Desktop.
Open Anaconda Navigator, launch JupyterLab, and navigate your directories to launch these notebooks.
git clone#
Git users type: git clone https://github.com/EastBayEv/SSDS-TAML.git
Install external libraries#
Install user-defined software libraries to enhance Python’s functionality. In a new notebook cell type !pip install <library name>
, e.g.:
!pip install pandas
!pip install seaborn
