Search across fields in Python
Python interview exercise on Practical, difficulty 2 of 3. Solve it in the editor beside a worked example, or cold in Interview mode with the example hidden; the tests run the moment you do.
Write search_rows(rows, query) that returns the row dicts in which any value contains the query, ignoring case and surrounding whitespace in the query. Values may be numbers; compare their text. An empty query matches every row.
Each exercise pairs a worked example with a twin problem to solve in a real editor; the tests run the moment you do. Interview mode hides the example: solve it from memory, without the hint or the solution, and it counts as solved cold. Progress is saved in your browser, and in your account if you sign in.
