I've been studying Python seriously for about eight months while working full time as a physical therapist, so most of my coding happens late at night or on weekends. I understand the larger concepts fairly well, but I often get stuck on small details and feel tempted to paste a working snippet from a search result without fully understanding it.
I want my code to work, but I also want to understand why it works. I've tried looking at a solution, hiding it, and reconstructing it from memory. Sometimes that helps, but other times I waste most of my short study session staring at the problem.
What helped you develop the ability to reason through unfamiliar problems instead of immediately looking up the answer? Was there a change in how you approached learning, or is it mostly a matter of getting enough practice?

It can also help to reduce automatic assistance while practicing. Turn off inline completions or make suggestions appear only when you request them. That prevents the editor from filling in the first idea before you’ve formed one yourself. Use references when needed, but make a habit of pausing first, writing down your own approach, and then checking it against the available solutions.
When you’re genuinely stuck, ask for a hint rather than a complete solution. Be specific: ask what assumption is wrong, what concept to review, or what the next useful observation would be. That keeps you involved in making the connection yourself. Also, don’t force every problem into one 45-minute session. Leaving it overnight and returning to it later can be more productive than struggling while exhausted.
There’s no substitute for working through difficult problems. Books, documentation, source code, and debugging are all useful, but they become learning tools only when you actively test your understanding. Try changing the example, rewriting it another way, removing pieces, and predicting the output before running it. The initial version may be slower, but repeated hands-on debugging builds the instinct you’re looking for.
I usually read several approaches instead of grabbing the first answer. Then I compare them against the requirements of my project, decide which tradeoffs matter, and either adapt one or write my own version. Copying a useful technique is fine if you can explain it, modify it, and predict how it will behave. The goal isn’t to avoid every reference; it’s to avoid outsourcing all of your thinking.
Looking up a solution isn’t automatically bad. The important part is treating it like a worked example rather than a magic spell. Ask what problem it solves, what assumptions it makes, and how you would recognize the same pattern somewhere else. Then close it and rebuild a smaller version from memory. Programming is a lot like chess: learning a technique matters, but practice is what teaches you when and why to use it.
Breaking the example into tiny pieces helped me a lot. I’ll comment each line with what I think it does, add a few print statements, and compare my guesses with what actually happens. The mistakes are usually what make the idea stick.
