## Teknik Detaylar

Python'un modern versiyonlarında **`async` ve `await`** sözdizimi ile **"coroutines"**  kullanan **"asenkron kod"** desteğine sahiptir.

Bu ifadeyi aşağıdaki bölümlerde daha da ayrıntılı açıklayalım:

* **Asenkron kod**
* **`async` ve `await`**
* **Coroutines**

## Asenkron kod

			return buf.Bytes(), err
		}
	case madmin.ProfilerGoroutines:
		prof.ext = "txt"
		prof.record("goroutine", 1, "before")
		prof.record("goroutine", 2, "before,debug=2")
		prof.stopFn = func() ([]byte, error) {
			var buf bytes.Buffer
			err := pprof.Lookup("goroutine").WriteTo(&buf, 1)
			return buf.Bytes(), err
		}
	case madmin.ProfilerTrace:
		dirPath, err := os.MkdirTemp("", "profile")

Всю функциональность асинхронного программирования с использованием `async` и `await`
часто обобщают словом "корутины". Они аналогичны <abbr title="Goroutines">"горутинам"</abbr>, ключевой особенности
языка Go.
