Handling Exceptions with try and except

The try...except statement is used to handle exceptions (errors) that may occur during program execution.

Handling exceptions enhances program stability and protects users and data from unexpected errors.

Code that might cause an exception is written inside a try block, while the code to handle the exception, if it occurs, is written inside an except block.

Copy
try:
    result = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero.")

In the example above, 10 / 0 raises a ZeroDivisionError, an exception that occurs when dividing a number by zero. This exception is handled by the except block, allowing the program to continue running without interruption.

You can use multiple except blocks to handle different types of exceptions. Each block corresponds to a specific type of exception.

Copy
try:
    # Code that may raise different types of exceptions
    ...
except ZeroDivisionError:
    print("Cannot divide by zero.")
except ValueError:
    print("Invalid input.")
except Exception as e:
    print(f"An unexpected error occurred: {e}")
