## Technical Details { #technical-details }

Modern versions of Python have support for **"asynchronous code"** using something called **"coroutines"**, with **`async` and `await`** syntax.

Let's see that phrase by parts in the sections below:

* **Asynchronous Code**
* **`async` and `await`**
* **Coroutines**

## Asynchronous Code { #asynchronous-code }

			// And should not expect any more results.
			bi, err := getMetacacheBlockInfo(fi, partN)
			internalLogIf(ctx, err)
			if err != nil || bi.EOS {
				// We are done and there are no more parts.
				return entries, io.EOF
			}
			if bi.endedPrefix(o.Prefix) {
				// Nothing more for prefix.
				return entries, io.EOF
			}
			partN++
			retries = 0
