Why Your Python Code Works But Still Gives Wrong Output
Your Python code runs perfectly.
No errors. No crashes.
But the output is completely wrong.
This usually happens because of a “logic assumption error” — not a syntax mistake.
Here are the 3 most common reasons:
1️⃣ Wrong understanding of the problem You think you're solving X, but the question actually expects Y. 👉 Example: treating input as string instead of integer
2️⃣ Hidden edge cases Your code works for normal inputs, but fails on:
empty values
negative numbers
large inputs
3️⃣ Misplaced conditions or loops Even a small mistake like wrong indentation or condition order can completely change the output.
💡 How to fix it (practical method):
Print intermediate values (use debugging)
Test with multiple inputs (not just one)
Manually trace your code step-by-step
Re-read the question after coding
Most students don’t struggle with Python syntax.
They struggle with thinking like the program.
That’s why platforms like AssignmentDude are useful — they don’t just fix the code, they explain where your logic broke so you don’t repeat the same mistake.
Once you start focusing on logic instead of just code, debugging becomes much easier.
