If your Python code displays an error message instead of showing you the results you want, it means there are errors or bugs in your code. These messages can be difficult to understand, but they tell you exactly the types of errors in your Python code and how you can fix them. So in this article, I will walk you through the types of errors in Python so that you can understand the errors in your code and how to fix them.
Types Of Errors in Python
Whenever you get an error in your Python code, just look for that error in the command prompt or terminal. It shows you which line the error is in. Then if you know where the error is, you can fix it easily. But understanding the types of errors in Python is very important for correcting them and also for coding interviews as a Python developer. So let’s take a look at the types of errors in Python.
Syntax Errors:
Syntax refers to the structure of instructions in a programming language. The syntax of Python is very user-friendly and readable for beginners, so you will only find such errors when you are new to the Python programming language. Syntax errors occur when you type something wrong; you could have missed part of a statement or misspelt it. To correct these errors, you can go to the line where the error is and correct what you entered incorrectly.
Indentation Errors:
Python is a simple language compared to languages like Java and C++ because it uses indentation to display the start and end of a block of code instead of curly brackets. Indentation errors occur when you make a mistake with the code structure. For example, if a line of code ends with a colon, you must indent the next line. Python automatically indents after the colon, but if you get an indentation error, be sure to add four spaces after a colon in the next line.
Type Errors:
Type errors are errors related to data types. This happens when you put the wrong type of data in the wrong place in your code. For example, if the code expects a number but you give a string, you will face a type error.
Name Errors:
A name error occurs when you try to use a variable or function that has not been defined yet. To avoid such errors in your Python code, make sure to define all variables and functions at the start of the program or before using them.
Logic Errors:
Sometimes you don’t get any errors, but your code doesn’t work the way you want it to. This type of error is a logical error. This means that there is nothing wrong with the code regarding indentation and syntax but the logic of the code or algorithm used is incorrect. To correct these errors, make sure you have written the correct logic in your code.
