The use of nested loops (for and while) demonstrates my ability to navigate and manipulate complex data structures because handling nested dictionaries (beanBags and recipes) requires a clear understanding of Python's data structures and the ability to iterate through them accurately.

The creation and use of the “made_a_recipe” and “ingredient_check” lists show proficiency in element-wise data validation. “ingredient_check” ensures that all necessary ingredients are available before a recipe is made. “made_a_recipe” ensures the code can repeat the order again from the beginning, which is analogous to data cleaning and validation in analytics—ensuring that datasets are complete and accurate before proceeding with analysis.
