What is the difference between an error and an exception in programming?

In programming, error and exception are different concepts:

• Error is a problem that usually occurs due to incorrect user actions, invalid data, or system failures. Errors are often irreversible and can lead to program crashes.

• Exception is an event that disrupts the normal flow of program execution but can be handled using exception handling mechanisms (try/catch). Exceptions allow the program to respond appropriately to unforeseen situations, such as a missing file or division by zero.

Example:

try:
    result = 10 / 0  # will raise ZeroDivisionError
except ZeroDivisionError:
    print("Division by zero is not possible")

Here, division by zero is an exception that can be handled, whereas an error is a broader concept that includes unhandled failures.
