Summary of Changes

Hello @holtskinner, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a minor but significant enhancement to the existing answer_query_sample.py script. The primary goal is to demonstrate how to include a user_pseudo_id when making an answer query, which is useful for tracking or personalization, aligning the sample with broader documentation for the Discovery Engine's answer functionality.

Highlights

  • Sample Code Enhancement: The answer_query_sample function call in discoveryengine/answer_query_sample.py has been updated to include an optional user_pseudo_id parameter.

Code Review

This pull request adds the user_pseudo_id parameter to the answer_query sample. The hardcoded value could be improved to better guide developers on its intended use. I've provided a suggestion to use a more descriptive placeholder and a more informative comment to encourage the use of unique identifiers, which is the best practice for this field.

The user_pseudo_id field is intended to be a unique identifier for each end-user to enable analytics and personalization. Using a static, hardcoded string like "user-pseudo-id" in a sample is misleading because developers might copy this non-unique value, which would defeat the purpose of the field.

To align with best practices, I recommend using a more descriptive placeholder and an improved comment to guide users towards providing a unique value, such as a UUID.

Suggested change
user_pseudo_id="user-pseudo-id", # Optional: Add user pseudo-identifier for queries.
user_pseudo_id="a-unique-user-id", # Optional: A unique identifier for the end user. We recommend using a randomly generated UUID.

None of the changes you added to this file are related to the original file's linting errors.

At a guess you ran black on the entire folder, and black doesn't abide by google's import sorting (through flake8-import-order).
