In programming, errors are inevitable. Whether it’s a user input error, a file not found, or a network issue, your Python applications need to be prepared to handle unexpected situations gracefully.
This is where exception handling comes into play, providing a structured way to catch and manage errors, ensuring your code runs smoothly and avoiding abrupt crashes or unexpected behavior.
Understanding Exceptions
An exception is an error that occurs during the execution of a program. When an exceptional situation arises, such as dividing by zero or attempting to access a non-existent file, Python raises an exception. If left unhandled, these exceptions can cause your program to terminate abruptly, potentially leading to data loss or other undesirable consequences.
Python’s exception handling mechanism allows you to catch and handle these exceptional situations, giving you the opportunity to take appropriate actions, such as logging the error, displaying a user-friendly message, or attempting alternative operations.
Here’s a simple example that demonstrates exception handling in Python:
