How is error handling with exceptions implemented in Python and how to use them correctly?

Error handling in Python is done using the try-except construct. The try block contains code that may raise an exception, and the except block contains code to handle that exception.

Proper use of exceptions includes:

• Catching only those exceptions that you expect and can handle.
• Not using an empty except without specifying the exception type, to avoid hiding errors.
• Using finally for code that must run in any case (for example, closing files).

Example:

try:
    result = 10 / 0
except ZeroDivisionError:
    print("Division by zero is not possible")
finally:
    print("Operation completed")

This approach helps make the program more robust and controllable when errors occur.
