What is the difference between 'content' and 'text'

The requests.Response class documentation has more details:

r.text is the content of the response in Unicode, and r.content is the content of the response in bytes.

It seems clear from the documentation is that r.content

You can also access the response body as bytes, for non-text requests:

 >>> r.content

If you read further down the page it addresses for example an image file

To some extent, text is nothing, but a sugar-coated version of content.

import requests
response = requests.get("https://httpbin.org/get")
response.text == response.content.decode(encoding == response.encoding)
True

All internet content is received in the form of bytes. Choose response.text for textual responses and use response.content for binary files like images or PDF
