I've completed several Python courses, including CS50P and Google's automation course, and I've also worked on personal projects. Even so, I still struggle when I'm faced with a blank file and often depend on AI to generate solutions. I found exercises like PyLings helpful for reinforcing the basics, but I'd like to become more comfortable designing and writing code myself. What practice methods, exercises, or habits helped you improve your coding fluency?

Practice with one small exercise every day, especially exercises that describe practical situations rather than only testing isolated syntax. Platforms such as Exercism can be useful because they give you realistic problems and let you compare different approaches after trying them yourself.
The main way to build fluency is to keep writing code regularly. AI can still be part of your workflow, but try to decide whether you’re using it to learn and check your thinking or simply to avoid doing the thinking yourself. Understanding logic, architecture, and problem-solving takes time, and there isn’t really a shortcut for that.
That makes sense. At the moment I’m reviewing AI-generated code much more often than writing my own, so I’d like to gradually reduce that dependence.
The blank-page problem usually isn’t caused by forgetting syntax. It’s the challenge of breaking a vague idea into small, manageable pieces. Before writing code, spend 15–20 minutes describing what the program should do in plain language. Turn those steps into a rough list of functions, then implement one small piece at a time. This gives you a plan instead of asking AI to do the planning for you.
This is similar to solving a word problem in math: the difficult part is often figuring out what the problem is asking and how to break it down.
Repeat common patterns until they become familiar: file handling, loops, dictionaries, classes, API requests, testing, and basic project structure. You don’t need to memorize everything, but recognizing a useful starting pattern makes new projects feel much less intimidating. Another good routine is to write a short specification, list a few example inputs and outputs, and sketch the functions before using autocomplete or AI. Once you have your own attempt, use AI as a reviewer for bugs, assumptions, and missing tests rather than as the primary author.
I like the idea of practicing common boilerplate and preparing examples before starting. That should make it easier to get past the initial hesitation.
Thanks, I’ve heard of Exercism before, so I’m going to give it a try.
