## 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>

            String line = br.readLine();
            while (line != null) {
                lineNumber++;
                gatherDeadUserGuideLinksInLineReleaseNotes(sourceFile, line, lineNumber, errorsForFile);
                gatherDeadSamplesLinksInLineReleaseNotes(sourceFile, line, lineNumber, errorsForFile);
                gatherDeadJavadocLinksInLineReleaseNotes(sourceFile, line, lineNumber, errorsForFile);

                }
            }

            // 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 {

                }
                valueLines.add(line);
                while (!line.isEmpty() && contains(WHITE_SPACE, line.charAt(0))) {
                    line = line.substring(1, line.length());
                }
                buffer.append(line);
                if (!combine) {
                    break;
                }
            }
            return buffer.toString();

                }
                valueLines.add(line);
                while (!line.isEmpty() && contains(WHITE_SPACE, line.charAt(0))) {

                }
            }
            return buffer.toString();

### Upgrading the Chart

You can use Helm to update MinIO version in a live release. Assuming your release is named as `my-release`, get the values using the command:

```bash
helm get values my-release > old_values.yaml
```

But, sadly, you get nothing useful:

### 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

                regex.find(line)?.let {
                    dependencies.add(replaceProjectDependency(line.trim()))
                }
            }
        }
        return dependencies
    }

    private fun replaceProjectDependency(line: String): String {
        val projectDependencyRegex = Regex("""project\(["']([^"']+)["']\)""")
        return line.replace(projectDependencyRegex) { match ->
