对于这些情况，你可以使用Python的技术，将 `dict` 与 `**dict_to_unpack` 解包：
```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}
new_dict = {**old_dict, "new key": "new value"}
```

这里， new_dict 将包含来自 old_dict 的所有键值对加上新的键值对：
```python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```

syntax = "proto2";

package k8s.io.apimachinery.pkg.runtime;

// Package-wide variables from generator "generated".
option go_package = "k8s.io/apimachinery/pkg/runtime";

// RawExtension is used to hold extensions in external versions.
//
// To use this, make a field which has RawExtension as its type in your external, versioned
// struct, and Object in your internal struct. You also need to register your
// various plugin types.

## 2. Enable bucket lifecycle configuration

- Create a bucket lifecycle configuration which expires the objects under the prefix `old/` on `2020-01-01T00:00:00.000Z` date and the objects under `temp/` after 7 days.
- Enable bucket lifecycle configuration using `mc`:

```sh
$ mc ilm import play/testbucket <<EOF
{
    "Rules": [
        {

	}
	ps.Lock()
	defer ps.Unlock()

	sub := &Sub[T]{ch: subCh, types: Mask(mask.Mask()), filter: filter}
	ps.subs = append(ps.subs, sub)

	// We hold a lock, so we are safe to update
	combined := Mask(atomic.LoadUint64(&ps.types))
	combined.Merge(Mask(mask.Mask()))
	atomic.StoreUint64(&ps.types, uint64(combined))

	go func() {
		<-doneCh

		ps.Lock()

		iamLogIf(GlobalContext, errors.New("WARNING: no cached IAM listing found"))
		return nil
	}

	// Scan STS users on disk and purge expired ones. We do not need to hold a
	// lock with store.lock() here.
	stsAccountsFromStore := map[string]UserIdentity{}
	stsAccPoliciesFromStore := xsync.NewMapOf[string, MappedPolicy]()
	for _, item := range iamListing[stsListKey] {

		diag.MockResource("GrandCastle"),
		"the castle is too old",
	)

	msgs := diag.Messages{firstMsg, secondMsg}
	output, _ := Print(msgs, LogFormat, false)

	g.Expect(output).To(Equal(
		"Error [B1] (SoapBubble) Explosion accident: the bubble is too big\n" +
			"Warning [C1] (GrandCastle) Collapse danger: the castle is too old",
	))
}

## 2. Create Kubernetes secret

[Kubernetes secrets](https://kubernetes.io/docs/concepts/configuration/secret) are intended to hold sensitive information.
We'll use secrets to hold the TLS certificate and key. To create a secret, update the paths to `private.key` and `public.crt`
below.

Then type

```sh

  @BeforeExperiment
  protected void setUp() {
    BitSet bitSet = new BitSet();
    for (int i = 0; i < OLD_WHITESPACE_TABLE.length(); i++) {
      bitSet.set(OLD_WHITESPACE_TABLE.charAt(i));
    }
    bitSet.clear(0);
    bitSet.clear(1);
    matcher = useNew ? CharMatcher.whitespace() : OLD_WHITESPACE;
    teststring = newTestString(new Random(1), bitSet, percentMatching);
  }
