An exception is an event which can terminate your program execution. This article explains the concept of exceptions as well as outlines how to handle exceptions.
What is an exception?
- In Python, an exception is an event that occurs during the execution of a program, disrupting the normal execution flow.
- Exceptions can be caused by various factors, such as invalid input, division by zero, or accessing nonexistent elements.
- Unlike syntax errors (which lead to program termination), exceptions allow the program to continue running, albeit with altered behavior.
Exception Object — Python Representation of Exception
- Like everything, an exception is also represented as an object in Python.
- An exception is an object derived from the
BaseExceptionclass. - It contains information about an error event that occurred within the code during execution.
The exception object includes:
1 — Error type (exception name)
2 — The state of the program when the error occurred
3 — An error message describing the event
