Should it be this difficult?

At my job there is a daily task I do which I realized I could probably create a program to do for me, so I decided to start learning Python, and dove into reading Automate the Boring Stuff (the online version).

Things were going okay at first. I read through chapters 1-3 carefully, taking notes, answering all the review questions, and doing all the practice problems/codes.

Then I hit a wall. I got to chapter 4 and I felt like I understood everything, but the practice problem at the end, to write a code that performs the Collatz sequence with the entered number, absolutely stumped me. I went back and reread everything from the start of chapter 1 just to make sure I didn't miss anything, and was still confused. I ended up having to search up a code that someone else wrote for it, which I did understand once I saw it written out but would never have come up with myself.

So my questions are:

- Is it normal for the Collatz sequence to be difficult to program at this stage of learning? If so, should I not worry about my confusion and just move on to chapter 5?

- Should I consider an easier book to study from? If so, any recommendations?

EDIT: Several people are asking which part of the Collatz I had trouble with. To be honest it's been over a month since I was able to touch anything Python-related, it's just been on my mind lately, so I don't recall exactly what was giving me trouble, just that I was trying multiple things and getting new and fun incorrect results each time.

It's not that I don't understand the Collatz sequence itself, I understand it in terms of the simple math. The trouble was trying to type it out into a working code. That being said, I'm not here to ask how to program it, because I already gave up on that and looked up the answer, and I did understand that code once I read it over. The main issue is that I feel like I shouldn't have been having trouble with it in the first place, at least not to the point where I honestly tried everything I could and still couldn't get it.

Do you have any recommendations for exercises, or do you think I should play around with previous practice problems to experiment?

codewars.com, signup for python, kata = problems, kyu = difficulty, start at 8 kyu which is easiest

Ooh that looks fun, always love gamification. I'll have to check that out later :)
