As a new student of python, I have only completed the first python certificate in Coursera prior to taking your course, it would be more encouraging if you had provide a simple example proceeding Lab questions #4, and #5...I would not have succeeded if I placed more time to work through those examples, and being disappointed in effort is generally not a good way to experience data analytics.
My mathematics skills are significantly greater than my python programming, and I am hopeful to get a better grasp of the programming.
Questions 4, and 5 were significantly harder, and even after viewing the solutions I must review carefully as I doubt I could have solved them from your lessons.
