 Welcome to the ML track. We hope you're really excited for this.  
 For starters we'll brush up your Python Skills. This includes your understanding of the following:

 We hope you're really excited to get started with actual Machine Learning. But just hold on!!  
 A big problem in machine learning algorithms is that, they're not humans. They are just bunch of formulas being applied in a loop of conditional statements.
