Clone from an existing GitHub repository

To illustrate, clone from a repo containing Python code (previously prepared by your peers)

1. Work on C: drive (network drives U and O appear to be slower)

cd C:\Users\user.name\DSI\

2. To illustrate, we will use the RADD consult as an example:

git clone -b pt2 https://github.com/BCCDC-DSI/RADD.git

3. We'll try out the Python code under part2_version2

cd C:\Users\user.name\DSI\RADD\workflows\part2_version2\

4. Create new virtual environment named radd-p2

python -m venv radd-p2

5. Activate it:

radd-p2\Scripts\activate

6. Build the virtual environment by download packages specified in the requirementsWindows.txt

pip install -r requirementsWindows.txt

7. Try executing one Python script created for this project:

python create_dataset.py

Python in VS Code

Creating new notebook

1. Go to Command Palette

2. Search by typing "Create":

3. Select the kernel
