python import random


def divide_numbers(a, b):

try:

result = a / b

return result

except ZeroDivisionError:

print("Error: Division by zero is not allowed.")

except TypeError:

print("Error: Input values must be numbers.")

except Exception as e:

print("An unexpected error occurred:", str(e))
# Testing the function

num1 = 10

num2 = 0

result = divide_numbers(num1, num2) print("Result:", result)

In this example, the `divide_numbers` function attempts to divide two numbers `a` and `b`. It employs a try-except block to handle potential errors that may occur during the division process. If a ZeroDivisionError occurs, it prints a custom error message. If a TypeError occurs (e.g., if non-numeric values are provided), it displays a different error message. Finally, if any other unexpected error occurs, it prints the specific error message.
