That error, however, points to line 2 in the example code:įile "C:\Users\Omisola Idowu\Desktop\Lato\soup\new.py", line 2, in
#Python script debug mode code
So if you encounter an error, pay attention to the line that Python is pointing to.įor example, the error in the example below is a type error because the code tries to concatenate dissimilar data types (a string and an integer). Thankfully, errors are line-bound in Python. Trace the Line Where the Error Comes From Merely tracing the line where they come from and rewriting your code can be key. There are many other exceptions that you can come across. However, invalid syntax connotes a wrong syntax somewhere, while AttributeError comes up when you try to call a wrong function from a class or an object.
Python usually states this on the last line of your error output.įor instance, unexpected EOF while parsing is always related to a missing parenthesis. One of the best ways to treat Python errors is to check the error description. You can use any or a combination of the following methods to debug Python. Ultimately, you'll encounter these errors more often while building real-life applications.Īlthough exceptions are frustrating, they don't take much to figure out and resolve if you're patient. Some errors also raise several exceptions at once. And that explains the typical detailed errors you sometimes encounter in Python.Įxceptions can arise when you use a built-in function, a library, or a Python framework. Invariably, this results in a chain of errors. Sometimes, a try.except block could contain several exceptions ( except keywords).
In essence, statements inside the except keyword are the exceptions to those in the try block, and Python raises them as errors. Executable commands are typically inside the try block.īut when the code inside try fails, Python executes those inside the except block. Python raises exceptions for errors using the try and except block. Python exceptions are a set of errors that arise while Python executes your code. Whenever Python can't interpret a code or a command, it raises an exception. So how can you understand and deal with them? These are some of the best ways you can debug your Python code. And as with any other programming language, errors can waste valuable time while coding with Python.
