This video will walk you through Amazon's 'Three Purchases' Python interview question solution.
We'll demonstrate how to apply a Lambda filter function based on a specific calculation, such as retrieving only orders for the year when a user has placed at least three orders. We'll explain how to tweak the Lambda function to return true or false values based on the number of rows in the group. With this knowledge, you can easily extract data subsets that meet your criteria.
