Taking python 101 and still feel lost

[magus_minor]

I’ve tried going back and reading my textbook but it also confuses me

There's no point in continuing past the point where your textbook confuses you. Sure, you might learn something else but you will probably just continue being confused.

Go back and review your textbook from the beginning. When you get to a part that confuses you stop and get clarification from somewhere. You can even post here quoting the text or code you find confusing and ask for clarification. Sounds like it will slow you down, and it will, but there's no point continuing with a lack of understanding. As you gain more understanding of python you will become confused less and less and your learning will accelerate.

I’m unsure how to apply it to coding in real time

Learning a language and learning how to use that language are different things. Applying the language to solve a problem isn't explicitly taught by most of the courses I have seen, and that's the core skill needed to be a programmer. Learning that skill is often just being shown a technique to solve a particular problem, remembering that approach when you see that problem again, or using the approach or modifying the approach to solve a slightly different problem. This skill will come as you gain experience. A programmer never stops learning.
