Try/except/else/finally

The complete error handling pattern.

python
def divide(a, b):
    try:
        result = a / b
    except ZeroDivisionError:
        print("Error: division by zero")
        return None
    except TypeError as e:
        print(f"Type error: {e}")
        return None
    else:
        print(f"Success: {a}/{b} = {result}")
        return result
    finally:
        print("Cleanup complete")

divide(10, 3)
print()
divide(10, 0)
print()
divide("10", 3)

else runs only if no exception was raised. finally always runs, even if an exception occurs or the function returns. Use finally for cleanup.
