Enjoy thislist of instructional videos I have found on YouTube. You may not expect YouTube to carry much content for serious Python programmers or students preparing for IT certification, but it is there - and available for no cost. You can be a beginner and develop your Python and data science knowledge for free. You can be an intermediate or advanced Pythonista and catch lectures and tutorials from others who are among the best in the world.
Whether the topic is web scraping, writing more efficient code, learning new data science methods, or familiarizing with a new library, you can usually find someone talking about it on YouTube. Now, forsake those petty political videos and never ending streams of social media clickbait. Brew a coffee and take an hour or two to understand concurrency or threading. Spend a weekend learning how use Beautiful Soup or Pandas. Watch and learn how Python programmers refine their workflow.
