The finally Block

The finally block runs no matter what. It executes whether an error occurs or not. It is typically used for cleanup tasks like closing open files or database connections.

try:
    print("Opening database...")
    x = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero!")
finally:
    print("Closing database connection... (Always Runs)")

Output:

Opening database...
Cannot divide by zero!
Closing database connection... (Always Runs)
