The previous Grab lecture was perfect, but this one is a bit difficult to follow. It is a course that requires basic skills, but I think it would have been a more cohesive education and one that students could easily understand if Grab had paid more attention to the content structure. When I ran the code in PyCharm, there were so many errors that I had to review and fix the code frequently, which made me feel a little uneasy while taking the class.
