Where can I find an example of working with VK ads.getDemographics in Python?

Question

Hello!
Actually the question is in the title. I want to receive statistics on cities. I read the documentation:
https://vk.com/dev/ads.getDemographics
It says that
impressions_rate is coming - part of the audience that viewed the ad, from 0 to 1
clicks_rate - part of the audience that clicked on the ad, from 0 to 1
And I would like see the number of views and clicks, not part of the audience. How can I do that?
