What debugging taught me about patience

The first time one of my programs crashed, I stared at the error message like it was written in another language. In a way, it was. Since then I've learned that bugs aren't failures. They're puzzles waiting to be solved.

Read the error, really read it

Most of the time, the computer tells you exactly what went wrong and where. Slowing down to actually read the message, including the line number, solves half my bugs.

def average(scores):
    return sum(scores) / len(scores)

average([])  # ZeroDivisionError!

This tiny function taught me to think about edge cases. What happens when the list is empty? Now I ask that question about everything I write.

Break it into small pieces

When something big doesn't work, I test the smallest part I can. Print a value. Check one function. Gradually the problem has nowhere left to hide.

Programming isn't about never making mistakes. It's about getting better at finding them.

It carries over

That same step-by-step thinking helps me in math, in science labs, and even in sports when I break down what went wrong on a missed shot. Coding didn't just teach me a language. It taught me a way to think.
