Update this course once again, please

[aderchox]

I've seen your post on Reddit where you said you had updated this course 5 years ago, but today Python 2 isn't even supported anymore, and the installation process of many of the tools used in the course has changed as well. I understood most of the parts since I'm not an absolute beginner and also there's already a great explanation for every bit of code. But for replicating the behavior shown in the course, there are minor updates that need to be applied and since I'm not a pro I cannot make pull requests with certainty. I hope you'll consider updating these amazing courses once again so they'll fit the thirst of the future Python learners as well! Best regards.
