## Set-Typen

Aber dann denken wir darüber nach und stellen fest, dass sich die Tags nicht wiederholen sollen, es sollen eindeutige Strings sein.

Python hat einen Datentyp speziell für Mengen eindeutiger Dinge: das <abbr title="Menge">`set`</abbr>.

	ctx := newContext(r, w, "KMSListKeys")
	defer logger.AuditLog(ctx, w, r, mustGetClaimsFromToken(r))

	// This only checks if the action (kms:ListKeys) is allowed, it does not check
	// each key name against the policy's Resources. We check that below, once
	// we have the list of key names from the KMS.
	objectAPI, _ := validateAdminReq(ctx, w, r, policy.KMSListKeysAction)
	if objectAPI == nil {
		return
	}

diagnostics help ensure that the underlying infrastructure that runs MinIO is configured correctly, and is functioning properly. This test is one-shot long running one, that is recommended to be run as soon as the cluster is first provisioned, and each time a failure scenario is encountered. Note that the test incurs majority of the available resources on the system. Care must be taken when using this to debug failure scenario, so as to prevent larger outages. Health tests can be triggered using...

```java
OkHttpClient client = new OkHttpClient.Builder()
    .connectionSpecs(Arrays.asList(ConnectionSpec.MODERN_TLS, ConnectionSpec.COMPATIBLE_TLS))
    .build();
```

					getSignature(getSigningKey(globalActiveCred.SecretKey, now,
						globalMinioDefaultRegion, serviceS3), "policy"),
				},
				"Policy": []string{"policy"},
			},
			expected: ErrNone,
		},
	}

	// Run each test case individually.
	for i, testCase := range testCases {
		_, code := doesPolicySignatureMatch(testCase.form)
		if code != testCase.expected {
