Prerequisites
Use official tool documentation and a dedicated local environment when a course needs packages.
Steps and expected result
The supplemental enrichment case-reference.py needs no third-party packages. Existing deep learning/BI/cloud courses have different prerequisites and explicitly documented runtime limits; a successful Python setup does not prove Spark, Docker or Power BI is installed.
python3 -m venv .venv
# Activate using the command for your OS and shell.
# Install only the requirements supplied by the specific course.Verification
Check the input row count and case control totals before attempting a larger exercise. Record your operating system/tool version when asking for support. Never include passwords or private source records.
Independent check
Explain which output proves the setup works and which capabilities remain untested. Do not disable security settings to make an exercise run.
Try the activity before reading its reference. Keep your sources, commands and assumptions with your work. Companion activities are unsaved self-practice and do not award a certificate or change lesson progress.
