1. Pause First, Don’t Slam the Keyboard
The worst thing you can do when an error appears is to start changing random lines and pressing Run again and again. That usually makes the code messier and harder to fix.
Instead, when you see an error:
-
Take a breath.
-
Don’t touch your code for a few seconds.
-
Remind yourself that every programmer gets errors, even experienced ones.
If you go into “panic mode”, your brain jumps straight to “I can’t do this”. If you slow down, your brain can start to notice simple things like spelling mistakes, missing brackets or wrong variable names.
2. Learn to Read the Error Message (From the Bottom Up)
Python is not trying to insult you when it shows red text. It is actually trying to help. The problem is that many students never really learn how to read error messages and just scroll past them.
Most tracebacks (the block of red text) follow the same pattern. The important parts are:
For example, you might see:
This is Python’s way of saying: “You’re trying to join text and a number together in a way that doesn’t work.”
Make it a habit to look at:
-
The error type (e.g. TypeError, NameError, SyntaxError).
-
The small message next to it.
-
The line of code it points to.
You don’t need to memorise every error type, but after a few assignments you’ll start recognising the common ones and fixing them faster.
3. Check the Line and the Lines Just Above It
Sometimes the line that Python points to is not the real problem. For example, if you forget a closing bracket or quote on one line, Python might complain on the next line.
When you get an error on line 25:
Ask yourself simple questions:
-
Are all brackets and quotes closed?
-
Is there a colon : after if, elif, else, for, while, def?
-
Did I spell the variable name the same way every time?
Very often, the bug is something tiny that your eyes skipped the first time.
4. Print Values to See What’s Really Happening
As a beginner, it is hard to “see” what your code is doing in your head. That’s normal. A good way to make your code less mysterious is to print important values while the programme runs.
For example, if you are getting a strange result in a loop, you can write:
Or if you keep getting a division error:
Printing values:
-
Shows you what the variables actually hold.
-
Helps you spot things like zero values, empty lists, or unexpected text.
-
Makes debugging feel like checking a simple sum rather than fighting with the whole script.
Once you’ve fixed the problem, you can remove or comment out the extra print lines.
5. Watch Your Data Types
A lot of Python errors in assignments come from mixing up data types. Common situations include:
-
Treating user input as a number without converting it.
-
Trying to add a string and an integer together.
-
Comparing text with numbers.
A simple way to stay calm here is to ask, for every variable: “What type is this right now?”
You can check it with:
If type(value) says , that means it’s a string. If you need a number, convert it using int() or float().
Getting used to data types turns a confusing error into a simple fix. Instead of “Python hates me”, it becomes “Oh, I forgot to convert this to an integer”.
6. Test Small Pieces Instead of the Whole Assignment
When your assignment gets longer, it’s very stressful to run the whole file and see an error somewhere in the middle. One way to reduce panic is to build and test your code in small chunks.
You can:
-
Write one function and test it properly before moving on.
-
Use a separate short file just to experiment with tricky parts.
-
Comment out sections temporarily so you can focus on only one part at a time.
For example, if your full programme reads a file, processes data and prints a report, you can first test only the file reading part. Once that works, move on to the processing. When that works, add the printing.
Step-by-step testing gives you small wins and keeps your confidence up.
7. Compare Your Code With the Brief, Not Just With the Error
Sometimes your code runs without errors, but the output is wrong. This can also cause panic, because there is no red message telling you what went wrong.
In these cases, go back to your task sheet or brief and check:
-
Did I follow the exact steps they asked for?
-
Did I use the right formulas or conditions?
-
Am I using the right inputs and test data?
You can also print out key results at each stage and compare them with what you expect. For example, if your assignment is about totals and averages, print the totals before calculating the average to see if they make sense.
Treat it like checking your maths homework: you’re looking for logic mistakes, not just code errors.
8. Use Comments to Keep Your Head Clear
When you are stressed, your code can start to feel like a wall of text. Adding short comments above tricky parts can make it easier to follow what you were trying to do, especially when you come back to it later.
For example:
The comments don’t need to be long or fancy. One simple sentence is enough. They act like mini reminders of your plan, so when something goes wrong you can see which step might be causing the issue.
9. Know When to Ask for Help (And What to Show)
Debugging is a skill, but you are not expected to fix every single problem on your own, especially at the start. What matters is how you ask for help.
Instead of saying “My code doesn’t work”, try to show:
For example:
“I’m getting a TypeError on line 18 when I try to add age to a string. I tried converting with int() but it still looks wrong. Can you help me see what I’m missing?”
This makes it much easier for a tutor, lab assistant or friend to guide you. You also learn more quickly because you stay involved in the process instead of just handing the problem over.
10. Remember That Debugging Is Part of Learning, Not a Sign of Failure
It’s very easy to think, “Other people just write perfect code, I’m the only one who keeps breaking things.” That is simply not true. Even professional developers spend a huge part of their week debugging, testing and fixing.
For your Python assignments, the goal is not to avoid errors completely. The goal is:
-
To stay calm when they appear.
-
To use error messages as information, not as insults.
-
To build a small routine: read the traceback, check the line, print values, test in smaller parts, and ask for help if needed.
If you keep practising this way, the red text on your screen will start to feel less scary and more like a normal part of writing code. Over time, you’ll spend less time panicking and more time actually solving the problem the assignment is asking for, and that’s what really leads to better marks.
