### Add types { #add-types }

Let's modify a single line from the previous version.

We will change exactly this fragment, the parameters of the function, from:

```Python
    first_name, last_name
```

to:

```Python
    first_name: str, last_name: str

                + (this.expiration - System.currentTimeMillis()) + "]";
    }

    /**
     * Get the time to live for this referral
     *
     * @return the ttl
     */
    public long getTtl() {
        return this.ttl;
    }

    /**
     * {@inheritDoc}
     *
     * @see java.lang.Object#hashCode()

public class DefaultClassRealmManager implements ClassRealmManager {
    public static final String API_REALMID = "maven.api";

    public static final String API_V4_REALMID = "maven.api.v4";

    /**
     * During normal command line build, ClassWorld is loaded by jvm system classloader, which only includes
     * plexus-classworlds jar and possibly javaagent classes, see https://issues.apache.org/jira/browse/MNG-4747.

## Multiple Workers { #multiple-workers }

You can start multiple workers with the `--workers` command line option:

//// tab | `fastapi`

If you use the `fastapi` command:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> run --workers 4 <u style="text-decoration-style:solid">main.py</u>

                }
            }

            // effective line, with indent and reset if end is colored
            line = indent + line + ("".equals(nextColor) ? "" : ANSI_RESET);

            if ((i == lines.length - 1) && (showErrors || (summary.getException() instanceof InternalErrorException))) {
                slf4jLogger.error(line, summary.getException());
            } else {

    private static final class Snippet {
        final int line;       // line of the [.multi-language-sample] header
        final Language lang;  // best-effort deduction (UNKNOWN allowed)

        Snippet(int line, Language lang) {
            this.line = line;
            this.lang = lang;
        }
    }

    private static final class Error {
        final int line;
        final String message;

    }

    /**
     * Checks if the buffer contains a line that matches the specified value (after trimming).
     *
     * @param value the value to search for in the buffered lines
     * @return true if a matching line is found, false otherwise
     */
    public boolean contains(final String value) {
        for (final String line : list) {
            if (line.trim().equals(value)) {
                return true;

    @Override
    public boolean hasNext() {
        if (line == EMPTY) {
            line = ReaderUtil.readLine(reader);
        }
        return line != null;
    }

    @Override
    public String next() {
        if (!hasNext()) {
            throw new NoSuchElementException();

        final String result = line;

        return result;

    This could have corrupted requests where multiple headers had the same name,
    as in cookies.
 *  Fix: Reject bad characters in the URL hostname. Previously characters like
    `\0` would cause a late crash when building the request.
 *  Fix: Allow interceptors to change the request method.
 *  Fix: Don’t use the request's `User-Agent` or `Proxy-Authorization` when
