How to Solve Python Problems on PyDebug – FAQ

A short guide to getting the most out of every problem on this page.

How do I solve a bug-fixing problem?

Read the description and the broken code carefully. Find the bug — a missing colon, an off-by-one index, a wrong operator, or a scope issue — fix it in the editor, then click Run to test and Submit Answer to check. The platform tells you instantly whether your solution is correct.

How do I answer an output-prediction question?

Read the snippet line by line and trace the values in your head or on paper. Consider side effects, function scope, loops, and conditionals, then type the exact expected output. Running the code shows you the real output so you can compare.

What should I do when I am stuck?

Use the hints panel for a nudge in the right direction, or open the Discussion tab to ask for help or look at how others solved the problem. Struggling first and then reading solutions is one of the fastest ways to learn.

What do the difficulty and topic tags mean?

Every problem shows its difficulty (easy, medium, hard) and its topic (such as loops, functions, lists, or recursion). Start with easy problems in familiar topics, then branch out. Solving across many topics builds a well-rounded foundation.

Do I earn XP for solving problems?

Yes. You earn XP the first time you solve a problem correctly, and solving at least one problem per day builds your daily streak. Track both on your dashboard.

Why can't I see the answer after submitting?

You will always see whether your answer is right or wrong. Model solutions and full explanations are available through the Discussion tab and for premium problems once unlocked, so everyone can learn from every attempt.
