Describe a Python design-and-coding approach in Colab

You are assigned a generic coding-and-design exercise to be completed in Python. Explain your end-to-end approach for executing this in Google Colab: how you would clarify functional requirements; choose core components and data structures; structure the solution into modules/classes and notebooks; handle I/O, configuration, logging, and error handling; write and run unit tests in Colab; assess time/space complexity and basic performance; manage dependencies and environment setup; and ensure reproducibility and documentation for reviewers.
