called exceptions. An exception is a Python object that represents an . error. When an error occurs during the execution of a program, an exception is said to have been raised. Such an exception needs to be handled by the programmer so that the program does not terminate abnormally. Therefore, while designing a program, a programmer
Exceptions: Exceptions occur when code that is otherwise syntactically correct, generates an error when we try to run it. These are slightly more challenging to debug, because we have to figure out why the error is occurring. Again, though, Python reports the error in a way that can help us. Let’s take the following simple script as an example.
Python 3 defines 63 built-in exceptions, and all of them form a tree-shaped hierarchy.
Python supports exception handling through mechanisms to catch and prevent errors. Exception handling makes programs more clear, robust and fault tolerant. The key takeaways from the document are that exception handling in Python is used to handle runtime errors.

Python represents exceptions as objects. In Python, all exceptions inherit from the BaseException class. Below, we see examples of the most common. Python exceptions. # IndexError exception: index out of range. A typical error that ocurrs. # its size. # TypeError exception: erroneus data type handling. # Correct data type handling.
In this article, you'll learn how to handle exceptions in your Python program using try, except and finally statements. This will motivate you to write clean, readable and efficient code in Python.
