Un **context manager** en Python es algo que puedes usar en un statement `with`, por ejemplo, `open()` puede ser usado como un context manager:

```Python
with open("file.txt") as file:
    file.read()
```

En versiones recientes de Python, también hay un **async context manager**. Lo usarías con `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```

			return "", err
		}
	}

	if underGoRoot {
		// Copy timezone file.
		//
		// Typical apps have the zoneinfo.zip in the root of their app bundle,
		// read by the time package as the working directory at initialization.
		// As we move the working directory to the GOROOT pkg directory, we
		// install the zoneinfo.zip file in the pkgpath.
		err := cp(

        // -1 in 16-bit is 0xFFFF
        assertEquals((byte) 0xFF, buffer[2]);
        assertEquals((byte) 0xFF, buffer[3]);

This will generate a TypeScript SDK in `./src/client`.

You can learn how to <a href="https://heyapi.dev/openapi-ts/get-started" class="external-link" target="_blank">install `@hey-api/openapi-ts`</a> and read about the <a href="https://heyapi.dev/openapi-ts/output" class="external-link" target="_blank">generated output</a> on their website.

### Using the SDK { #using-the-sdk }

### Файл `.env` { #the-env-file }

У вас может быть файл `.env` со следующим содержимым:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### Чтение настроек из `.env` { #read-settings-from-env }

Затем обновите ваш `config.py` так:
