The Cleanup | The Architect

Some magic spells leave a mess. Maybe you opened a portal, but forgot to close it.

Even if the spell fails (errors), we must clean up. We need a way to say: "Do this no matter what happens."

The `finally` Spell

The finally block creates a guarantee. It runs after the try and except blocks, always.

try:
  print("Opening box...")
  # Maybe error here
except:
  print("Something broke!")
finally:
  print("Closing box.") # This ALWAYS runs

The Unclosed Portal

The portal opens, but if teleport_hoppy crashes, it stays open! Dangerous.

Add the Cleanup

Add a finally: block inside the function.

Close it

Inside finally, print "Closing portal..." and set portal_status = "Closed". Then watch it run even after the crash!

finally is perfect for "cleaning up" — like saving a file, closing a connection, or resetting a switch, even if your main code explodes.

Solution:

def teleport_hoppy():
  global portal_status
  try:
      print("Opening portal...")
      print(1 / 0) # Crash!
      print("Teleporting...")
  except:
      print("Teleport failed!")
  finally:
      print("Closing portal...")
      portal_status = "Closed"

The code inside finally runs even if you return inside the try block!
It's the most reliable place to clean up resources (like closing files or database connections).
