        Filing feature requests is one of the most popular ways to contribute to Guava.


        Be aware, though: most feature requests are not accepted, even if they're suggested by
        a full-time Guava team member. [Feedback](https://stackoverflow.com/a/4543114) from our

        .build()
    val acceptedIssuers = handshakeCertificates.trustManager.acceptedIssuers
    val names =
      acceptedIssuers
        .map { it.subjectDN.name }
        .toSet()

    // It's safe to assume all platforms will have a major Internet certificate issuer.
    assertThat(names).matchesPredicate { strings ->
      strings.any { it.matches(Regex("[A-Z]+=Entrust.*")) }
    }
  }

Por exemplo, você poderia ter um arquivo `main.py` com:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | "Dica"

{!../../docs_src/python_types/tutorial009c.py!}
```

De parameter `name` is gedefinieerd als `Optional[str]`, maar is **niet optioneel**, je kunt de functie niet aanroepen zonder de parameter:

```Python
say_hi()  # Oh, nee, dit geeft een foutmelding! 😱
```

De `name` parameter is **nog steeds vereist** (niet *optioneel*) omdat het geen standaardwaarde heeft. Toch accepteert `name` `None` als waarde:

```Python

    } else {
      prefix_cmp = string(prefix) + "/";
      // The operation should fail if the provided name prefix has already been
      // used in this graph
      for (const auto& pair : g->name_map) {
        const string& name = pair.first;
        if ((name == prefix) || absl::StartsWith(name, prefix_cmp)) {
          status->status = InvalidArgument(
              "prefix [", prefix,

  // Subresource is one of the existing resource types.  "" means none.
  // +optional
  optional string subresource = 6;

  // Name is the name of the resource being requested for a "get" or deleted for a "delete". "" (empty) means all.
  // +optional
  optional string name = 7;
}

// ResourceRule is the list of actions the subject is allowed to perform on resources. The list ordering isn't significant,
