Debugging: Finding It Yourself

சுருக்கம்

Every beginner course stops at "and now it works". Then the learner goes home, changes one line, and has no method for what happens next. This segment is the method. One small program — a bill splitter, about twenty lines — gets broken repeatedly and you get it back. You will read a traceback properly instead of scrolling past it. You will cut a file in half with `exit()` and cut it in half again until two lines are left. You will comment out everything except one function and drive it directly. You will print a value raw, then stripped, then lowered, so you can see the transformation instead of reasoning about it. Then the gauntlet: missing colon, wrong quote characters, stray whitespace, indentation, `=` where you wanted `==`, a result you never stored, two functions with the same name, an input asked for twice, a `TypeError` on text that was never converted, and text glued together where you meant to add numbers. Six of those tell you something is wrong. The rest do not say a word, and those are the ones that reach other people.

1. 01 Reading What It Already Told You

   3 பாடங்கள்·1h 9m

   A traceback is read from the bottom. The last line is a sentence. The line number above it is where Python gave up, which is not always where you went wrong. Read it, then act. Guessing before…

2. 02 Elimination, Not Inspiration

   3 பாடங்கள்·1h 37m

   Real troubleshooting is elimination. You do not find the fault by thinking harder about the whole file; you find it by making the file smaller until there is nowhere left for it to hide.

3. 03 The Gauntlet

   One fix, one run. A file with four changes in it and a fresh error tells you nothing about which change caused what.

Debugging: Finding It Yourselfல் நான் என்ன கற்பேன்?

The half of programming nobody teaches. You take one working program, break it nine ways, and find every fault by elimination rather than by staring at it. Ends with the kind of bug that raises no error at all.
