Exporting only a specific set of pages in Python with requests

In this guide, we'll show you how to export only a specific set of pages from a document using Python and the requests 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:

import requests

# 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 = requests.post(
    'https://api.pdfshift.io/v3/convert/pdf',
    auth=('api', api_key),
    json=params
)
response.raise_for_status()

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

print('The PDF document was generated and saved to result.pdf')
