A set stores unique elements without preserving an ordering, making it useful when duplicate values must be eliminated. In a small Python task, it can collect randomly selected question IDs until the required count is reached. section 5.3.6
Selecting 35 unique question IDs
Check that at least 35 questions exist, create an empty set, repeatedly choose an available ID, and add it. Repeated choices do not create duplicates; convert the finished set to a list for the returned result. Validate the data shape carefully: SELECT * returns rows, whereas SELECT id returns IDs. section 5.3.6
Review these practical cautions before accepting generated code:
- Test the insufficient-data path and verify that the output contains exactly the requested number of unique values. section 5.3.6
