python
try:
# Code that might raise an error
result = 10 / 0 # Division by zero - ZeroDivisionError
except ZeroDivisionError as error:
# Error handling specific to ZeroDivisionError
print("Error: Division by zero is not allowed.")
print("Details:", error)
except Exception as error:
# Generic error handling for any other exception
print("An error occurred:", error)
else:
# Executed if no error occurred
print("Calculation successful. Result:", result)
finally:
# Executed regardless of whether an exception occurred or not
print("This code block is always executed.")

# Rest of the program continues...

In the above code snippet, we use a `try-except` block to handle potential errors. If a `ZeroDivisionError` occurs, it’s caught and handled specifically. If any other exception occurs, it’s caught by the generic `Exception` block. The `else` block is executed if no exception occurs, and the `finally` block always runs, regardless of whether an exception occurred or not.
