Problem You upload a file to your S3 bucket using the AWS CLI or SDK, and instead of a success message, you get: Error: 301 Moved Permanently The request didn’t fail — but it didn’t succeed either.

Each S3 bucket belongs to a specific AWS region. If your request goes to the wrong region or to the global endpoint ( s3.amazonaws.com ), S3 responds with a 301 redirect, telling your client to retry in the correct region. Howe...

  The Custom Conveyor: Building Your Own Iterators # python # coding # programming # softwaredevelopment Timothy understood how iterators worked, but Margaret's next challenge tested his knowledge: "The library needs a custom catalog browsing system. Patrons should view entries by decade, skip damaged records, and page through results fifty at a time. Build it using the Iterator Protocol." Margaret led him to the workshop where specialized conveyor systems were assembled. "You know how iterators work," she said. "Now you'll build your own custom conveyors for specific library needs." The Custom Iterator Need Timothy's catalog needed specialized iteration that built-in types couldn't provide: # Note: Examples use placeholder data structures and functions # In practice, replace with your actual implementation # The library's catalog - thousands of entries catalog = [ { " title " : " 1984 " , " author ...
