### Just Modern Python { #just-modern-python }

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md){.internal-link target=_blank}.

You write standard Python with types:

```Python

			certificate, err := certs.NewCertificate(env.Get(EnvKESClientCert, ""), env.Get(EnvKESClientKey, ""), loadX509KeyPair)
			if err != nil {
				return nil, err
			}
			certificate.Watch(ctx, 15*time.Minute, syscall.SIGHUP)

			conf.GetClientCertificate = func(*tls.CertificateRequestInfo) (*tls.Certificate, error) {
				cert := certificate.Get()
				return &cert, nil
			}
		}

		var caDir string

	}

	if len(poolIndices) > 0 && globalEndpoints[poolIndices[0]].Endpoints[0].IsLocal {
		go func() {
			// Resume decommissioning of pools, but wait 3 minutes for cluster to stabilize.
			if err := sleepContext(ctx, 3*time.Minute); err != nil {
				return
			}
			r := rand.New(rand.NewSource(time.Now().UnixNano()))
			for {
				if err := z.Decommission(ctx, poolIndices...); err != nil {

All replication failures are picked up by the scanner which runs at a one minute frequency, each time scanning up to a sixteenth of the namespace. Object versions marked `PENDING` or `FAILED` are re-queued for replication.

	c.Assert(err, nil)

	// Check if bucket modtime is consistent (not less than current time and not late more than 5 minutes)
	timeNow := time.Now().UTC()
	c.Assert(creationTime.Before(timeNow), true)
	c.Assert(timeNow.Sub(creationTime) < time.Minute*5, true)
}

// This tests validate if PUT handler can successfully detect signature mismatch.
