<｜begin▁of▁sentence｜>### Instruction:
As a fire inspector, you are conducting an assessment of a building to ensure it complies with fire codes and safety standards. While inspecting the building, you need to retrieve the status handler for the fire alarm system, if it has one, using the get_status_handler method from the FireAlarmSystem class.
### Response:
import idlelib.shell

# Assuming we have an instance of IDLE's Shell window
def get_idle_shell_status_handler(shell_window):
    status_handler = shell_window.get_status_handler()
    if status_handler is not None:
        return f'Status handler is available: {status_handler}'
    else:
        return 'No status handler is available.'

# Create a shell window instance (for demonstration only, typically the shell is part of IDLE's UI)
idle_shell_window = idlelib.shell.Shell()

# Get and print the status handler for this shell window
print(get_idle_shell_status_handler(idle_shell_window))
