Microsoft ❤️Python

This my keynote presentation given at PyConf++ 2020 Russia Online. I demonstrate a few different scanarios of using Python in Microsoft Azure, including Azure Notebooks, Cognitive Services, Bot Framework, Azure Functions and Storage. During the session, we togehter build an interactive virtual science art exhibit in the form of a telegram chatbot. The bot may still be available for you to try at @PeopleBlenderBot in Telegram.
