Prepare and pace your work
Review the prerequisites in the course overview before beginning this first milestone. Use each unit’s active-time estimate and pause at lesson boundaries. Plan another 2–4 hours for the milestone challenge, including rerunning checks and explaining your result.
Use Colab for notebook exercises and the workspace introduced in the units for local environment, packaging, and command-line tasks.
Connect the units
Finish with Pack a Moon-Garden Supply Box. Combine the milestone skills and check a changed condition. The challenge provides a contract, expected results, a hint, and self-review guidance.
