If something is wrong with your code, Python will try to help you by displaying an error message. These error messages are just bugs in your code. In this article, I’ll walk you through how to fix bugs in Python.
How To Find Bugs in Python?
The bugs might seem a little confusing at first, but they’ll give you clues as to why your program isn’t working and how to fix it. Python displays error messages in a red coloured text in the shell window. The program stops working when an error message appears. That message tells you which line of code caused the error.
When an error message appears in the shell, right-click on it and choose “Go to File / Line” from the drop-down menu. The IDLE editor jumps directly to this line of code so that you can start debugging.
Types of Errors in Python
Before we look at how to fix bugs in Python, let’s take a quick look at the types of bugs in Python. There are mainly 5 types of bugs in Python:
- Syntax errors: When you receive a syntax error message, it indicates that you typed something wrong.
- Indentation errors: Python uses indentation to understand where blocks of code start and end. An indentation error means that something is wrong with the way you have structured the code.
- Type errors: A type error is not a typing error. This means that your code has mixed one data type with another, for example mistaking numbers for strings.
- Name errors: A name error message appears if your code uses the name of a variable or function that has not yet been created.
- Logic errors: Sometimes you can tell something is wrong even though Python hasn’t given you an error message because your program isn’t doing what you expected. You may have a logic error.
How To Fix Bugs in Python?
Sometimes you might think that you can never make a program work, but don’t give up. If you follow all of the tips mentioned below, you will be able to identify and fix most bugs in Python:
- If you are creating projects that are already common among the coding community, try searching the internet for it using error as a keyword. You will have a good idea.
- Check if everything is spelt correctly.
- Check if you have any unnecessary spaces at the start of a line.
- Check to see if you’ve been confused with numbers for letters, such as 0 and O.
- Check if you’ve used upper and lower case letters in the correct places.
- Check if all open parentheses have a corresponding closing parenthesis.
- Check if all single and double quotes have a matching closing quote.
- Ask for help on platforms like Stackoverflow, you can even ask us in the comments section below.
- Always make sure to save your code after making any changes.
