By creating a function that is only dedicated to getting your user from a `username` (or any other parameter) independent of your *path operation function*, you can more easily reuse it in multiple parts and also add <abbr title="Automated test, written in code, that checks if another piece of code is working correctly.">unit tests</abbr> for it:

```Python hl_lines="36-42"

	// the http.Transport and should not be read, written or
	// closed by users of ClientTrace.

	// Reused is whether this connection has been previously
	// used for another HTTP request.
	Reused bool

	// WasIdle is whether this connection was obtained from an
