I’m currently learning Python and finding loops and conditionals a bit challenging. I understand the basic syntax, but when it comes to applying them in real-world scenarios, I often get confused. For example, I struggle with deciding when to use a ‘for’ loop versus a ‘while’ loop, and how to structure nested conditionals effectively. I’ve been practicing with some beginner projects, like creating simple calculators and text-based games, but I feel like I’m not making the progress I’d like. I’ve also tried following along with tutorials, but I think I need more hands-on practice and perhaps some guidance on best practices. Could anyone recommend resources or exercises that specifically focus on improving understanding and application of loops and conditionals in Python? Any tips or personal experiences would also be greatly appreciated.
I’d say always try starting with for loop. Python has many handy functions that makes for loop even more pleasure to use - ie. enumerate, zip. Check out also the built-in itertools module.
One obvious case for while loop might be infinite loops (with condition while True:), however in some cases that still can be imitated with for loop.
Generally though it doesn’t matter much which you will use first in your attempts. If chosen loop type won’t be helpful in achieving the task, you can always switch later. That applies also to completing it, once you know what is needed to make it work, it’s easier to see what might not be required. Working code is great point for refactoring and reflection.
Yup. Really the only way to improve is to try a lot of things and keep trying.
The first job of code is to work correctly. The second job of code is to be easy to maintain. The third job of code is to be efficient and elegant. I would worry about correctness first and then work on the other skills as you feel more comfortable with correctness.
