In this guide, we'll show you how to export only a specific set of pages from a document using Python and the aiohttp library to convert them to PDF using PDFShift's API.

When you're converting a document, you might want to export only a specific set of pages from a document. This can be done by setting the `pages` parameter to the request.

It behaves exactly like the page parameter you can see when you print a document from your browser.

It accepts the following pattern:

 * A number, such as `2`. This will print the page 2
 * A range, such as `2-4`. This will print the pages 2 to 4 (2, 3 and 4)
 * A list, such as `2,4,5,9`. This will print the pages 2, 4, 5 and 9


This way, you can only export the pages that you really need and get immediately the result you want in the PDF, without having to edit it.

Here's an example:

```python
import aiohttp, asyncio, json

# You can get an API key at https://pdfshift.io
api_key = 'sk_xxxxxxxxxxxx'

params = {
    'source': 'https://en.wikipedia.org/wiki/PDF',
    'pages': '2-4'
}

response = None
try:
    async with aiohttp.ClientSession() as session:
        async with session.post(
            'https://api.pdfshift.io/v3/convert/pdf',
            headers={'X-API-Key': api_key},
            json=params
        ) as response:
            if response.status >= 400:
                raise Exception('Invalid request: {}'.format(await response.text()))

            with open('result.pdf', 'wb') as f:
                f.write(await response.read())

            print('The PDF document was generated and saved to result.pdf')
except asyncio.TimeoutError:
    raise Exception('The request took too long to process')
except aiohttp.ClientError as e:
    raise Exception(f'An error occurred: {e}')
except Exception as e:
    # We highly recommend you to handle exceptions. Often, PDFShift will provide you with a clear explanation about what happened.
    # Moreover, in case of error, no PDF are returned !
    raise Exception(f'An error occurred: {e}')
```
