`Optional[Something]` মূলত `Union[Something, None]`-এর একটি শর্টকাট, এবং তারা সমতুল্য।

এর মানে হল, Python 3.10-এ, আপনি টাইপগুলির ইউনিয়ন ঘোষণা করতে `Something | None` ব্যবহার করতে পারেন:

=== "Python 3.10+"

    ```Python hl_lines="1"
    {!> ../../../docs_src/python_types/tutorial009_py310.py!}

                            + " (" + repository.getUrl() + ")");
        }

        if (file == null) {
            // TODO throw something instead?
            return true;
        }

        Date lastCheckDate;

        if (file.exists()) {
            lastCheckDate = new Date(file.lastModified());
        } else {

## Return Type and Data Filtering

Let's continue from the previous example. We wanted to **annotate the function with one type** but return something that includes **more data**.

We want FastAPI to keep **filtering** the data using the response model.

- plugin dependency metadata missing
- plugin dependency metadata retrieval problem
- plugin configuration problem
- plugin execution failure due to something that is know to possibly go wrong (like compilation failure)
- plugin execution error due to something that is not expected to go wrong (the compiler executable missing)
- asking to use a plugin for which you do not have a version defined - tools to easily select versions

            }
        """

        then:
        succeeds "tasks" // succeeds because we don't fail on invalid usage, and don't fail due to unbound inputs

        where:
        code << [
            'something.$(1)',
            'this.$("$name")',
            'foo.bar().$("a" + "b")',
        ]
    }

    def "dollar var is only detected with no explicit receiver - #code"() {
        when:

`Optional[Something]` is actually a shortcut for `Union[Something, None]`, they are equivalent.

This also means that in Python 3.10, you can use `Something | None`:

=== "Python 3.10+"

    ```Python hl_lines="1"
    {!> ../../../docs_src/python_types/tutorial009_py310.py!}
    ```

            type('Task').property('prop')
            kind('something cool')
            includeLink()
        }

        then:
        outputEquals """
Type 'Task' property 'prop' is missing something cool.

Reason: A property without annotation isn't considered during up-to-date checking.

Possible solutions:
  1. Add something cool.
  2. Mark it as @Internal.

`Optional[Something]` насправді є скороченням для `Union[Something, None]`, вони еквівалентні.

Це також означає, що в Python 3.10 ви можете використовувати `Something | None`:

=== "Python 3.8 і вище"

    ```Python hl_lines="1  4"
    {!> ../../../docs_src/python_types/tutorial009.py!}
    ```

            plugin.setGroupId(tok[0]);
            plugin.setArtifactId(tok[1]);
            plugin.setVersion(tok[2]);
            goal = tok[3];

            // This won't be valid, but it constructs something easy to read in the error message
            for (int idx = 4; idx < tok.length; idx++) {
                goal += ":" + tok[idx];
            }
        } else if (numTokens == 3) {
