@k0wsk1 If you are a beginner I would suggest you to go through this article " Learning Python: From Zero to Hero " ( https://goo.gl/PXKWL5 ) on Medium.com . It quickly cover basics of Python and put you on track with Python learning. Once you are done with the article I would recommend you to register with codecademy and take this free course on Python "Learn Python" https://www.codecademy.com/learn/learn-python . By the time you complete this course on codecademy you should feel confident enough to learn Data science, Machine learning, Blockchain, Web development and many other domains where Python takes the lead.
