Intellisense on data structure not working

This should be an easy question. I'm using the community edition of PyCharm.

I'm using the requests library to do this in the code:

r = requests.get(url)

I'm used to typing r. and letting intellisense show me what's in r but I'm not sure if this is a limitation of this particular IDE or language since I'm not familiar with python too much.

I also did type(r) and it returned <class 'requests.models.Response'>

Thanks.
