PyCharm not suggesting anything

I see there have been quite a few tickets about similar issues but none of them had any solution.

PyCharm does not suggest methods while typing (for any library).

For example, in the screenshot below, I would expect to see methods I can call on service in the autosuggest popover (like I would in WebStorm or PhPStorm). I only get "not", "par" and "main" every single time.

Everything is enabled in settings in accordance to all the other posts on the topic. Is something off or is this just not a feature like with Javascript or PHP?

Below is an example for PhpStorm which shows me all the methods I can call on $response. I want to achieve the same thing in PyCharm.
