python selenium downloading embedded pdf

[damian0612]

I've navigated to a page to download a pdf that is a report showing information I've asked for. However, I can't seem to download it because of the way the information is being displayed. When I inspect the pdf, here is what I see:

<embed id="plugin" type="application/x-google-chrome-pdf" src="https://uk.ixl.com/analytics/students-quickview-pdf" stream-url="chrome-extension://mhjfbmdgcfjbbpaeojofohoefgiehjai/0129a32b-174c-4e06-b6e5-0f332f853591" headers="cache-control: no-cache

so when I try to download the pdf using urllib.request.urlretrieve(pdfUrl, pdfname) (with the pdfUrl = to the src in the code above) I get the error urllib.error.HTTPError: HTTP Error 403: Forbidden and when I load the the source page you can tell from the link that it is a generic page and for all reports and actually just gives you an error, so it seems as if the data is being streamed to the pdf if I'm right looking at where it says stream-url="chrome-extension://mhjfbmdgcfjbbpaeojofohoefgiehjai/d5f1b753-2bf4-468c-8c35-be6f1629ecc8". Any ideas how I can download this page? I might be missing something but as a home user I'm up to speed with python too much, thanks.
