Por exemplo, você pode definir um arquivo `main.py` com o seguinte código:

```Python hl_lines="3"
import os

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

/// dica

O segundo parâmetro em <a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> é o valor padrão para o retorno.

		want := 309
		for i := 0; i < n; i++ {
			f = append(f, f...)
			want *= 2
		}
		b.Run(fmt.Sprint(len(f)/(1<<10), "K"), func(b *testing.B) {
			b.ReportAllocs()
			b.SetBytes(int64(len(f)))
			b.ResetTimer()
			var record sql.Record
			for i := 0; i < b.N; i++ {

/// details | What that command means

* `echo "*"`: will "print" the text `*` in the terminal (the next part changes that a bit)
* `>`: anything printed to the terminal by the command to the left of `>` should not be printed but instead written to the file that goes to the right of `>`

* kubectl: fixes a regression with --use-openapi-print-columns that would not print object contents ([#65600](https://github.com/kubernetes/kubernetes/pull/65600), [@liggitt](https://github.com/liggitt))

- Extend discovery GroupManager with Group lister interface ([#127524](https://github.com/kubernetes/kubernetes/pull/127524), [@mjudeikis](https://github.com/mjudeikis)) [SIG API Machinery]
- Fix kubectl doesn't print image volume when kubectl describe a pod with that volume ([#126706](https://github.com/kubernetes/kubernetes/pull/126706), [@carlory](https://github.com/carlory)) [SIG CLI]
