So, I am currently using "Automate the Boring Stuff with Python." I currently finished the first three chapters of the program. Then, I did the practice project called the "The Collatz Sequence". However, I was not able to solve the problem. Honestly, it really frustrated me that I was not able to solve it. I really want to learn python and I want to do it properly. But I am unsure how to go about it. Should I go back and reviewed the previous chapters to better grasp the concepts? Should I keep moving forward? Should I look use websites like Codewars to practice? I am just kind of lost because I do want to learn effectively as possible. Just wanted advice and suggestions from others.
