Stop writing code immediately. Plan your logic first. Draw a flowchart. Do manual math. Then write your Python code.
I solved two classic problems to test this process.
Problem 1: Sum of N numbers.
- I started with a while loop. It worked.
- I switched to a for loop. It looked cleaner.
- I used a math formula. It was instant. The fastest loop is the one you do not run.
Problem 2: Sum of prime numbers.
- I checked every number. It was slow.
- I skipped even numbers. It became faster.
- I skipped even divisors. It became smarter.
My process followed four steps:
- Working code.
- Cleaner code.
- Faster code.
- Smarter logic.
Do not worry about a perfect solution at first. Make it work first. Make it better next. This is how you learn to think like a programmer.
