I've attempted to search GitHub issues for an example or documentation on how to list blocks programmatically within a task, but it appears there were no issues found that match this description.
As such, the best course of action to find specific details on how to programmatically list blocks within a Prefect task is to review the Prefect 2.0 documentation on the official website, check out the Prefect Discourse community forums for user-contributed examples, or explore the source code of Prefect on GitHub for the client functions related to block interaction. Often, these resources are more comprehensive and up-to-date, offering guidance on advanced usage patterns including programmatic access and manipulation of Prefect features such as blocks.
If you have further questions or require additional assistance, feel free to ask!
