Translates to:

print(not Button.CENTER in inventor_hub.buttons.pressed())
while not not Button.CENTER in inventor_hub.buttons.pressed():
    wait(1)

But it would be cleaner to generate:

print(Button.CENTER not in inventor_hub.buttons.pressed())
while Button.CENTER in inventor_hub.buttons.pressed():
    wait(1)
