Python 3 Requests Proxy Error

[mattl1598]

I'm working on my A-Level Computer Science Project part of which grabs data from the google books API. I have some working code which does this and I wrote into my program last year.

Over the summer, the school updated all of the computers to windows 10 and since then, the requests module is unable to connect to the API to get the data.

It shouldn't be the OS update since I run Windows 10 at home and it works just fine there. 

The error below indicates that it's a proxy issue which must be from the schools proxy filter for websites like youtube and facebook but they had the same filter last year and I can still view the data from the API by pasting the address into Chrome.

Does anyone know a workaround or solution that means the program can still grab the data?
