Python requests arguments/dealing with api pagination

Question

I'm playing around with the Angel List (AL) API and want to pull all jobs in San San Francisco. Since I couldn't find an active Python wrapper for the api (if I make any headway, I think I'd like to make my own), I'm using the requests library.

The AL API's results are paginated, and I can't figure out how to move beyond the first page of the results.

Here is my code:

import requests
r_sanfran = requests.get("https://api.angel.co/1/tags/1664/jobs").json()
r_sanfran.keys()
# returns [u'per_page', u'last_page', u'total', u'jobs', u'page']
r_sanfran['last_page']
#returns 16
r_sanfran['page']
# returns 1

I tried adding arguments to requests.get, but that didn't work. I also tried something really dumb - changing the value of the 'page' key like that was magically going to paginate for me.

eg. r_sanfran['page'] = 2

I'm guessing it's something relatively simple, but I can't seem to figure it out so any help would be awesome.

Thanks as always.

Angel List API documentation if it's helpful.

Improving on @alecxe's answer: if you use a Python Generator and a requests HTTP session you can improve the performance and resource usage if you are querying lots of pages or very large pages.

import requests

session = requests.Session()

def get_jobs():
    url = "https://api.angel.co/1/tags/1664/jobs" 
    first_page = session.get(url).json()
    yield first_page
    num_pages = first_page['last_page']

    for page in range(2, num_pages + 1):
        next_page = session.get(url, params={'page': page}).json()
        yield next_page

for page in get_jobs():
    # TODO: process the page
